The ONFI specification states that devices do not need to support
sequential reads across LUN boundaries. In order to prevent such event
from happening and possibly failing, let's introduce the concept of
"pause" in the sequential read to handle these cases. The first/last
pages remain the same but any time we cross a LUN boundary we will end
and restart (if relevant) the sequential read operation.

If both ftl.ko and gluebi.ko are loaded, the notifier of ftl
triggers NULL pointer dereference when trying to access
‘gluebi->desc’ in gluebi_read().
ubi_gluebi_init
ubi_register_volume_notifier
ubi_enumerate_volumes
ubi_notify_all
gluebi_notify nb->notifier_call()

ftl_add_mtd tr->add_mtd()
scan_header
mtd_read
mtd_read_oob
mtd_read_oob_std
gluebi_read mtd->read()
gluebi->desc - NULL
Detailed reproduction information available at the Link [1],
In the normal case, obtain gluebi->desc in the gluebi_get_device(),
and access gluebi->desc in the gluebi_read(). However,
gluebi_get_device() is not executed in advance in the
ftl_add_mtd() process, which leads to NULL pointer dereference.
The solution for the gluebi module is to run jffs2 on the UBI
volume without considering working with ftl or mtdblock [2].
Therefore, this problem can be avoided by preventing gluebi from
creating the mtdblock device after creating mtd partition of the
type MTD_UBIVOLUME.

conntrack zones are heavily used by tools like openvswitch to run
multiple virtual "routers" on a single machine. In this context each
conntrack zone matches to a single router, thereby preventing
overlapping IPs from becoming issues.
In these systems it is common to operate on all conntrack entries of a
given zone, e.g. to delete them when a router is deleted. Previously this
required these tools to dump the full conntrack table and filter out the
relevant entries in userspace potentially causing performance issues.
To do this we reuse the existing CTA_ZONE attribute. This was previous
parsed but not used during dump and flush requests. Now if CTA_ZONE is
set we filter these operations based on the provided zone.
However this means that users that previously passed CTA_ZONE will
experience a difference in functionality.
Alternatively CTA_FILTER could have been used for the same
functionality. However it is not yet supported during flush requests and
is only available when using AF_INET or AF_INET6.

If a transaction is aborted, we should mark the to-be-released NEWSET dead,
just like commit path does for DEL and DESTROYSET commands.
In both cases all remaining elements will be released via
set->ops->destroy().
The existing abort code does NOT post the actual release to the work queue.
Also the entire __nf_tables_abort() function is wrapped in gc_seq
begin/end pair.
Therefore, async gc worker will never try to release the pending set
elements, as gc sequence is always stale.
It might be possible to speed up transaction aborts via work queue too,
this would result in a race and a possible use-after-free.
So fix this before it becomes an issue.

same is true for the cancellation data, it must be

also requires destroying the mutex in case we lost

There are currently multiple levels of fall back if an RT allocation
can not be satisfied:
1) xfs_rtallocate_extent extends the minlen and reduces the maxlen due
to the extent size hint. If that can't be done, it return -ENOSPC
and let's xfs_bmap_rtalloc retry, which then not only drops the
extent size hint based alignment, but also the minlen adjustment
2) if xfs_rtallocate_extent gets -ENOSPC from the underlying functions,
it only drops the extent size hint based alignment and retries
3) if that still does not succeed, xfs_rtallocate_extent drops the
extent size hint (which is a complex no-op at this point) and the
minlen using the same code as (1) above
4) if that still doesn't success and the caller wanted an allocation
near a blkno, drop that blkno hint.
The handling in 1 is rather inefficient as we could just drop the
alignment and continue, and 2/3 interact in really weird ways due to
the duplicate policy.
Move aligning the min and maxlen out of xfs_rtallocate_extent and into
a helper called directly by xfs_bmap_rtalloc. This allows just
continuing with the allocation if we have to drop the alignment instead
of going through the retry loop and also dropping the perfectly usable
minlen adjustment that didn't cause the problem, and then just use
a single retry that drops both the minlen and alignment requirement
when we really are out of space, thus consolidating cases (2) and (3)
above.

xfs_bmap_rtalloc is a bit of a mess in terms of calculating the locally
need variables. Reorder them a bit so that related code is located
next to each other - the raminlen calculation moves up next to where
the maximum len is calculated, and all the prod calculation is move
into a single place and rearranged so that the real prod calculation
only happens when it actually is needed.

Take mp->m_perag_lock for deletions from the perag radix tree in
xfs_initialize_perag to prevent racing with tagging operations.
Lookups are fine - they are RCU protected so already deal with the
tree changing shape underneath the lookup - but tagging operations
require the tree to be stable while the tags are propagated back up
to the root.
Right now there's nothing stopping radix tree tagging from operating
while a growfs operation is progress and adding/removing new entries
into the radix tree.
Hence we can have traversals that require a stable tree occurring at
the same time we are removing unused entries from the radix tree which
causes the shape of the tree to change.
Likely this hasn't caused a problem in the past because we are only
doing append addition and removal so the active AG part of the tree
is not changing shape, but that doesn't mean it is safe. Just making
the radix tree modifications serialise against each other is obviously
correct.

Move logic that is common between QAT GEN4 accelerators to the
qat_common folder. This includes addresses of CSRs, setters and
configuration logic.
When moved, functions and defines have been renamed from 4XXX to GEN4.
Code specific to the device is moved to the file adf_gen4_hw_data.c.
Code related to configuration is moved to the newly created
adf_gen4_config.c.
This does not introduce any functional change.

Add accel_dev as parameter of the function uof_get_num_objs().
This is in preparation for the introduction of the QAT 420xx driver as
it will allow to reconfigure the ae_mask when a configuration that does
not require all AEs is loaded on the device.
This does not introduce any functional change.

Move the function get_service_enabled() from adf_4xxx_hw_data.c to
adf_cfg_services.c and rename it as adf_get_service_enabled().
This function is not specific to the 4xxx and will be used by
other QAT drivers.
This does not introduce any functional change.

When the mpi_ec_ctx structure is initialized, some fields are not
cleared, causing a crash when referencing the field when the
structure was released. Initially, this issue was ignored because
memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag.
For example, this error will be triggered when calculating the
Za value for SM2 separately.

All devices compatible with SM8150 QCE (so SM8250 and newer) do not have
clock inputs (clocks are handled by secure firmware), so explicitly
disallow the clocks in the bindings.
