With external metadata device, flush requests are not passed down to the
data device.
Fix this by submitting the flush request in dm_integrity_flush_buffers. In
order to not degrade performance, we overlap the data device flush with
the metadata device flush.

There wasn't ever a real need to log an error in the kernel log for
ioctls issued with insufficient permissions. Simply return an error
and if an admin/user is sufficiently motivated they can enable DM's
dynamic debugging to see an explanation for why the ioctls were
disallowed.

This reverts commit 757055ae8dedf5333af17b3b5b4b70ba9bc9da4e.
The commit caused that ttynull was used as the default console
on several systems[1][2][3]. As a result, the console was
blank even when a better alternative existed.
It happened when there was no console configured
on the command line and ttynull_init() was the first initcall
calling register_console().
Or it happened when /dev/ did not exist when console_on_rootfs()
was called. It was not able to open /dev/console even though
a console driver was registered. It tried to add ttynull console
but it obviously did not help. But ttynull became the preferred
console and was used by /dev/console when it was available later.
The commit tried to fix a historical problem that have been there
for ages. The primary motivation was the commit 3cffa06aeef7ece30f6
("printk/console: Allow to disable console output by using console=""
or console=null"). It provided a clean solution for a workaround
that was widely used and worked only by chance.
This revert causes that the console="" or console=null command line
options will again work only by chance. These options will cause that
a particular console will be preferred and the default (tty) ones
will not get enabled. There will be no console registered at
all. As a result there won't be stdin, stdout, and stderr for
the init process. But it worked exactly this way even before.
The proper solution has to fulfill many conditions:
+ Register ttynull only when explicitly required or as
the ultimate fallback.
+ ttynull should get associated with /dev/console but it must
not become preferred console when used as a fallback.
Especially, it must still be possible to replace it
by a better console later.
Such a change requires clean up of the register_console() code.
Otherwise, it would be even harder to follow. Especially, the use
of has_preferred_console and CON_CONSDEV flag is tricky. The clean
up is risky. The ordering of consoles is not well defined. And
any changes tend to break existing user settings.
Do the revert at the least risky solution for now.

The final step in regulator_register() is to call
regulator_resolve_supply() for each registered regulator
(including the one in the process of being registered). The
regulator_resolve_supply() function first checks if rdev->supply
is NULL, then it performs various steps to try to find the supply.
If successful, rdev->supply is set inside of set_supply().
This procedure can encounter a race condition if two concurrent
tasks call regulator_register() near to each other on separate CPUs
and one of the regulators has rdev->supply_name specified. There
is currently nothing guaranteeing atomicity between the rdev->supply
check and set steps. Thus, both tasks can observe rdev->supply==NULL
in their regulator_resolve_supply() calls. This then results in
both creating a struct regulator for the supply. One ends up
actually stored in rdev->supply and the other is lost (though still
present in the supply's consumer_list).
Here is a kernel log snippet showing the issue:
[ 12.421768] gpu_cc_gx_gdsc: supplied by pm8350_s5_level
[ 12.425854] gpu_cc_gx_gdsc: supplied by pm8350_s5_level
[ 12.429064] debugfs: Directory 'regulator.4-SUPPLY' with parent
'17a00000.rsc:rpmh-regulator-gfxlvl-pm8350_s5_level'
already present!
Avoid this race condition by holding the rdev->mutex lock inside
of regulator_resolve_supply() while checking and setting
rdev->supply.

devm_platform_get_irqs_affinity()
The current check of nvec < minvec for nvec returned from
platform_irq_count() will not detect a negative error code in nvec.
This is because minvec is unsigned, and, as such, nvec is promoted to
unsigned in that check, which will make it a huge number (if it contained
-EPROBE_DEFER).
In practice, an error should not occur in nvec for the only in-tree
user, but add a check anyway.

hwmon, specifically hwmon_num_channel_attrs, expects the config
array in the hwmon_channel_info structure to be terminated by
a zero entry. amd_energy does not honor this convention. As
result, a KASAN warning is possible. Fix this by adding an
additional entry and setting it to zero.

When non-fatal error like line-reset happens, ufshcd_err_handler() starts
to abort tasks by ufshcd_try_to_abort_task(). When it tries to issue a task
management request, we hit two warnings:
WARNING: CPU: 7 PID: 7 at block/blk-core.c:630 blk_get_request+0x68/0x70
WARNING: CPU: 4 PID: 157 at block/blk-mq-tag.c:82 blk_mq_get_tag+0x438/0x46c
After fixing the above warnings we hit another tm_cmd timeout which may be
caused by unstable controller state:
__ufshcd_issue_tm_cmd: task management cmd 0x80 timed-out
Then, ufshcd_err_handler() enters full reset, and kernel gets stuck. It
turned out ufshcd_print_trs() printed too many messages on console which
requires CPU locks. Likewise hba->silence_err_logs, we need to avoid too
verbose messages. This is actually not an error case.

Phil Oester reported that a fix for a possible buffer overrun that I sent
caused a regression that manifests in this output:
Event Message: A PCI parity error was detected on a component at bus 0 device 5 function 0.
Severity: Critical
Message ID: PCI1308
The original code tried to handle the sense data pointer differently when
using 32-bit 64-bit DMA addressing, which would lead to a 32-bit dma_addr_t
value of 0x11223344 to get stored
32-bit kernel: 44 33 22 11 ?? ?? ?? ??
64-bit LE kernel: 44 33 22 11 00 00 00 00
64-bit BE kernel: 00 00 00 00 44 33 22 11
or a 64-bit dma_addr_t value of 0x1122334455667788 to get stored as
32-bit kernel: 88 77 66 55 ?? ?? ?? ??
64-bit kernel: 88 77 66 55 44 33 22 11
In my patch, I tried to ensure that the same value is used on both 32-bit
and 64-bit kernels, and picked what seemed to be the most sensible
combination, storing 32-bit addresses in the first four bytes (as 32-bit
kernels already did), and 64-bit addresses in eight consecutive bytes (as
64-bit kernels already did), but evidently this was incorrect.
Always storing the dma_addr_t pointer as 64-bit little-endian,
i.e. initializing the second four bytes to zero in case of 32-bit
addressing, apparently solved the problem for Phil, and is consistent with
what all 64-bit little-endian machines did before.
I also checked in the history that in previous versions of the code, the
pointer was always in the first four bytes without padding, and that
previous attempts to fix 64-bit user space, big-endian architectures and
64-bit DMA were clearly flawed and seem to have introduced made this worse.

Due to insufficient locking, qeth_core_set_online() and
qeth_dev_layer2_store() can run in parallel, both attempting to load &
setup the discipline (and stepping on each other toes along the way).
A similar race can also occur between qeth_core_remove_device() and
qeth_dev_layer2_store().
Access to .discipline is meant to be protected by the discipline_mutex,
so add/expand the locking in qeth_core_remove_device() and
qeth_core_set_online().
Adjust the locking in qeth_l*_remove_device() accordingly, as it's now
handled by the callers in a consistent manner.

When qeth_dev_layer2_store() - holding the discipline_mutex - waits
inside qeth_l*_remove_device() for a qeth_do_reset() thread to complete,
we can hit a deadlock if qeth_do_reset() concurrently calls
qeth_set_online() and thus tries to aquire the discipline_mutex.
Move the discipline_mutex locking outside of qeth_set_online() and
qeth_set_offline(), and turn the discipline into a parameter so that
callers understand the dependency.
To fix the deadlock, we can now relax the locking:
As already established, qeth_l*_remove_device() waits for
qeth_do_reset() to complete. So qeth_do_reset() itself is under no risk
of having card->discipline ripped out while it's running, and thus
doesn't need to take the discipline_mutex.

pd and then after uctx->cntxt_pd is freed, the variable pd is passed to
function _ocrdma_dealloc_pd() which dereferences pd directly or through
its call to ocrdma_mbx_dealloc_pd().
Reorder the free using the variable pd.

When mlx5_create_flow_group() fails, ft->g should be
freed just like when kvzalloc() fails. The caller of
mlx5e_create_l2_table_groups() does not catch this
issue on failure, which leads to memleak.

mlx5e_create_ttc_table_groups() frees ft->g on failure of
kvzalloc(), but such failure will be caught by its caller
in mlx5e_create_ttc_table() and ft->g will be freed again
in mlx5e_destroy_flow_table(). The same issue also occurs
in mlx5e_create_ttc_table_groups(). Set ft->g to NULL after
kfree() to avoid double free.

Prior to this patch, configuring speed to 50G with autoneg off over
devices supporting 50G per lane failed.
Support for 50G per lane introduced a new set of link-modes, on which
driver always performed a speed validation as if only legacy link-modes
were configured. Fix driver speed validation to force setting autoneg
over 56G only if in legacy link-mode.

sop_drop_qpn field in the cqe is used by two features, in SWITCHDEV mode
to restore the chain id in case of a miss and in LEGACY mode to support
skbedit mark action. In build RX skb, the skb mark field is set regardless
of the configured mode which cause a corruption of the mark field in case
of switchdev mode.
Fix by overriding the mark value back to 0 in the representor tc update
skb flow.

Adding vf VLANID for the first time, or after having cleared previously
defined VLANID works fine, however, attempting to change an existing vf
VLANID clears the rules on the firmware, but does not add new rules for
the new vf VLANID.
Fix this by changing the logic in function esw_acl_egress_lgcy_setup()
so that it will always configure egress rules.

Connection counters may be shared for both directions when the counter
is used for connection aging purposes. However, if TC flow
accounting is enabled then a unique counter is required per direction.
Instantiate a unique counter per direction if the conntrack accounting
extension is enabled. Use a shared counter when the connection accounting
extension is disabled.
