If the sector number is too high, dm_table_find_target() should return a
pointer to a zeroed dm_target structure (the caller should test it with
dm_target_is_valid).
However, for some table sizes, the code in dm_table_find_target() that
performs btree lookup will access out of bound memory structures.
Fix this bug by testing the sector number at the beginning of
dm_table_find_target(). Also, add an "inline" keyword to the function
dm_table_get_size() because this is a hot path.

In commit 6096d91af0 ("dm space map metadata: fix occasional leak
of a metadata block on resize"), we refactor the commit logic to a new
function 'apply_bops'. But when that logic was replaced in out() the
return value was not stored. This may lead out() returning a wrong

When btree_split_beneath() splits a node to two new children, it will
allocate two blocks: left and right. If right block's allocation
failed, the left block will be unlocked and marked dirty. If this
happened, the left block'ss content is zero, because it wasn't
initialized with the btree struct before the attempot to allocate the
right block. Upon return, when flushing the left block to disk, the
validator will fail when check this block. Then a BUG_ON is raised.
Fix this by completely initializing the left block before allocating and
initializing the right block.

If the inode from afs_do_lookup() is an error other than ENOENT, or if it
is ENOENT and afs_try_auto_mntpt() returns an error, the trace event will
try to dereference the error pointer as a valid pointer.
Use IS_ERR_OR_NULL to only pass a valid pointer for the trace, or NULL.
Ideally the trace would include the error value, but for now just avoid
the oops.

Fix a leak on the cell refcount in afs_lookup_cell_rcu() due to
non-clearance of the default error in the case a NULL cell name is passed
and the workstation default cell is used.
Also put a bit at the end to make sure we don't leak a cell ref if we're
going to be returning an error.
This leak results in an assertion like the following when the kafs module is
unloaded:

We can't rely on ->peer_features in calc_target() because it may be
called both when the OSD session is established and open and when it's
not. ->peer_features is not valid unless the OSD session is open. If
this happens on a PG split (pg_num increase), that could mean we don't
resend a request that should have been resent, hanging the client
indefinitely.
In userspace this was fixed by looking at require_osd_release and
get_xinfo[osd].features fields of the osdmap. However these fields
belong to the OSD section of the osdmap, which the kernel doesn't
decode (only the client section is decoded).
Instead, let's drop this feature check. It effectively checks for
luminous, so only pre-luminous OSDs would be affected in that on a PG
split the kernel might resend a request that should not have been
resent. Duplicates can occur in other scenarios, so both sides should
already be prepared for them: see dup/replay logic on the OSD side and
retry_attempt check on the client side.

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

We should keep the case of "#define debug_align(X) (X)" for all arches
without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who

especially for embedded systems. This is also the intention of the
original #ifdef... statement and still valid for now.
Note that this still keeps the effect of the fix of the following commit,
