Recently we notice that ext4 filesystem would occasionally fail to read
metadata from disk and report error message, but the disk and block
layer looks fine. After analyse, we lockon commit 88dbcbb3a484
("blkdev: avoid migration stalls for blkdev pages"). It provide a
migration method for the bdev, we could move page that has buffers
without extra users now, but it lock the buffers on the page, which
breaks the fragile metadata read operation on ext4 filesystem,
ext4_read_bh_lock() was copied from ll_rw_block(), it depends on the
assumption of that locked buffer means it is under IO. So it just
trylock the buffer and skip submit IO if it lock failed, after
wait_on_buffer() we conclude IO error because the buffer is not
uptodate.
This issue could be easily reproduced by add some delay just after
buffer_migrate_lock_buffers() in __buffer_migrate_folio() and do
fsstress on ext4 filesystem.
EXT4-fs error (device pmem1): __ext4_find_entry:1658: inode #73193:
comm fsstress: reading directory lblock 0
EXT4-fs error (device pmem1): __ext4_find_entry:1658: inode #75334:
comm fsstress: reading directory lblock 0
Fix it by removing the trylock logic in ext4_read_bh_lock(), just lock
the buffer and submit IO if it's not uptodate, and also leave over
readahead helper.

The original i_version implementation was pretty expensive, requiring a
log flush on every change. Because of this, it was gated behind a mount
option (implemented via the MS_I_VERSION mountoption flag).
Commit ae5e165d855d (fs: new API for handling inode->i_version) made the
i_version flag much less expensive, so there is no longer a performance
penalty from enabling it. xfs and btrfs already enable it
unconditionally when the on-disk format can support it.
Have ext4 ignore the SB_I_VERSION flag, and just enable it
unconditionally. While we're in here, mark the i_version mount
option Opt_removed.
[ Removed leftover bits of i_version from ext4_apply_options() since it
now can't ever be set in ctx->mask_s_flags -- lczerner ]

Setting ib1 state to MTK_FOE_STATE_UNBIND in __mtk_foe_entry_clear
routine as done by commit 0e80707d94e4c8 ("net: ethernet: mtk_eth_soc:
fix typo in __mtk_foe_entry_clear") breaks flow offloading, at least
on older MTK_NETSYS_V1 SoCs, OpenWrt users have confirmed the bug on
MT7622 and MT7621 systems.
Felix Fietkau suggested to use MTK_FOE_STATE_INVALID instead which
works well on both, MTK_NETSYS_V1 and MTK_NETSYS_V2.

Jiri Pirko says:
====================
devlink: sanitize per-port region creation/destruction
Currently the only user of per-port devlink regions is DSA. All drivers
that use regions register them before devlink registration. For DSA,
this was not possible as the internals of struct devlink_port needed for
region creation are initialized during port registration.
This introduced a mismatch in creation flow of devlink and devlink port
regions. As you can see, it causes the DSA driver to make the port
init/exit flow a bit cumbersome.
Fix this by introducing port_init/fini() which could be optionally
called by drivers like DSA, to prepare struct devlink_port to be used
for region creation purposes before devlink port register is called.
Tested by Vladimir on his setup.

Since dsa_port_devlink_setup() and dsa_port_devlink_teardown() are
already called from code paths which only execute once per port (due to
the existing bool dp->setup), keeping another dp->devlink_port_setup is
redundant, because we can already manage to balance the calls properly
(and not call teardown when setup was never called, or call setup twice,
or things like that).

Commit 3122433eb533 ("net: dsa: Register devlink ports before calling DSA driver setup()")
moved devlink port setup to be done early before driver setup()
was called. That is no longer needed, so move the devlink port
initialization back to dsa_port_setup(), as the first thing done there.
Note there is no longer needed to reinit port as unused if
dsa_port_setup() fails, as it unregisters the devlink port instance on
the error path.

There is a desire to simplify the dsa_port registration path with
devlink, and this involves reworking a bit how user ports which fail to
connect to their PHY (because it's missing) get reinitialized as UNUSED
devlink ports.
The desire is for the change to look something like this; basically
dsa_port_setup() has failed, we just change dp->type and call
dsa_port_setup() again.
-/* Destroy the current devlink port, and create a new one which has the UNUSED
- * flavour.
- */
-static int dsa_port_reinit_as_unused(struct dsa_port *dp)
+static int dsa_port_setup_as_unused(struct dsa_port *dp)
{
- dsa_port_devlink_teardown(dp);
dp->type = DSA_PORT_TYPE_UNUSED;
- return dsa_port_devlink_setup(dp);
+ return dsa_port_setup(dp);
}
For an UNUSED port, dsa_port_setup() mostly only calls dsa_port_devlink_setup()
anyway, so we could get away with calling just that. But if we call the
full blown dsa_port_setup(dp) (which will be needed to properly set
dp->setup = true), the callee will have the tendency to go through this
code block too, and call dsa_port_disable(dp):
switch (dp->type) {
case DSA_PORT_TYPE_UNUSED:
dsa_port_disable(dp);
break;
That is not very good, because dsa_port_disable() has this hidden inside
of it:
if (dp->pl)
phylink_stop(dp->pl);
Fact is, we are not prepared to handle a call to dsa_port_disable() with
a struct dsa_port that came from a previous (and failed) call to
dsa_port_setup(). We do not clean up dp->pl, and this will make the
second call to dsa_port_setup() call phylink_stop() on a dangling dp->pl
pointer.
Solve this by creating an API for phylink destruction which is symmetric
to the phylink creation, and never leave dp->pl set to anything except
NULL or a valid phylink structure.

registered area
Move port_setup() op to be called before devlink_port_register() and
port_teardown() after devlink_port_unregister().
Note it makes sense to move this alongside the rest of the devlink port
code, the reinit() function also gets much nicer, as clearly the fact that
port_setup()->devlink_port_region_create() was called in dsa_port_setup
did not fit the flow.

pre-register/post-unregister functions
Lifetime of some of the devlink objects, like regions, is currently
forced to be different for devlink instance and devlink port instance
(per-port regions). The reason is that for devlink ports, the internal
structures initialization happens only after devlink_port_register() is
called.
To resolve this inconsistency, introduce new set of helpers to allow
driver to initialize devlink pointer and region list before
devlink_register() is called. That allows port regions to be created
before devlink port registration and destroyed after devlink
port unregistration.

The devices of the versaclk clock generator family use an I2C control bus.
IO access on an I2C bus can fail for various reasons.
The driver currently ignores the return value of most IO operations. This
results in silent failure. To avoid this check the return value and in case
of an error abort the operation and propagate the error code to the caller.

Pull clk driver fixes from Stephen Boyd:
"Here's the last batch of clk driver fixes for this release.
These patches fix serious problems, for example, i.MX has an issue
where changing the NAND clk frequency hangs the system. On Allwinner
H6 the GPU is being overclocked which could lead to long term hardware
damage.
And finally on some Broadcom SoCs the serial console stopped working
because the clk tree hierarchy description got broken by an
inadvertant DT node name change. That's fixed by using
'clock-output-names' to generate a stable and unique name for clks so
the framework can properly link things up.
There's also a couple build fixes in here. One to fix CONFIG_OF=n
builds and one to avoid an array out of bounds bug that happens during
clk registration on microchip. I hope that KASAN would have found that
OOB problem, but probably KASAN wasn't attempted. Instead LLVM/clang
compilation caused an oops, while GCC didn't"

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fail the 'perf test record' entry on error, fixing a regression where
just setup stuff like allocating memory and not the actual things
being tested failed.
- Fixup disabling of -Wdeprecated-declarations for the python scripting
engine, the previous attempt had a brown paper bag thinko.
- Fix branch stack sampling test to include sanity check for branch
filter on PowerPC.
- Update is_ignored_symbol function to match the kernel ignored list,
fixing running the 'perf test' entry that compares resolving symbols
from kallsyms to resolving from vmlinux.
- Augment the data source type with ARM's neoverse_spe list, the
previous code was limited in its search resolving the data source.
- Fix some clang 5 variable set but unused cases.
- Get a perf cgroup more portably in BPF as the
__builtin_preserve_enum_value builtin is not available in older
versions of clang. In those cases we can forgo BPF's CO-RE (Compile
Once, Run Everywhere).

strerror() expects a positive errno, however variable err will never be
positive when an error occurs. This causes bpftool to output too many
"unknown error", even a simple "file not exist" error can not get an
accurate message.
This patch fixed all "strerror(err)" patterns in bpftool.
Specially in btf.c#L823, hashmap__append() is an internal function of
libbpf and will not change errno, so there's a little difference.
Some libbpf_get_error() calls are kept for return values.
Changes since v1: https://lore.kernel.org/bpf/SY4P282MB1084B61CD8671DFA395AA8579D539@SY4P282MB1084.AUSP282.PROD.OUTLOOK.COM/
Check directly for NULL values instead of calling libbpf_get_error().
