sc->ip is the inode that's being scrubbed, which means that it's not set
for scrub types that don't involve inodes. If one of those scrubbers
(e.g. inode btrees) returns EDEADLOCK, we'll trip over the null pointer.
Fix that by reporting either the file being examined or the file that
was used to call scrub.

Pull xfs updates from Darrick Wong:
"The notable user-visible addition this cycle is ability to remove
space from the last AG in a filesystem. This is the first of many
changes needed for full-fledged support for shrinking a filesystem.
Still needed are (a) the ability to reorganize files and metadata away
from the end of the fs; (b) the ability to remove entire allocation
groups; (c) shrink support for realtime volumes; and (d) thorough
testing of (a-c).
There are a number of performance improvements in this code drop: Dave
streamlined various parts of the buffer logging code and reduced the
cost of various debugging checks, and added the ability to pre-create
the xattr structures while creating files. Brian eliminated
transaction reservations that were being held across writeback (thus
reducing livelock potential.
Other random pieces: Pavel fixed the repetitve warnings about
deprecated mount options, I fixed online fsck to behave itself when a
readonly remount comes in during scrub, and refactored various other
parts of that code, Christoph contributed a lot of refactoring this
cycle. The xfs_icdinode structure has been absorbed into the (incore)
xfs_inode structure, and the format and flags handling around
xfs_inode_fork structures has been simplified. Chandan provided a
number of fixes for extent count overflow related problems that have
been shaken out by debugging knobs added during 5.12.
Summary:
- Various minor fixes in online scrub.
- Prevent metadata files from being automatically inactivated.
- Validate btree heights by the computed per-btree limits.
- Don't warn about remounting with deprecated mount options.
- Initialize attr forks at create time if we suspect we're going to
need to store them.
- Reduce memory reallocation workouts in the logging code.
- Fix some theoretical math calculation errors in logged buffers that
span multiple discontig memory ranges but contiguous ondisk
regions.
- Speedups in dirty buffer bitmap handling.
- Make type verifier functions more inline-happy to reduce overhead.
- Reduce debug overhead in directory checking code.
- Many many typo fixes.
- Begin to handle the permanent loss of the very end of a filesystem.
- Fold struct xfs_icdinode into xfs_inode.
- Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
ioctl.
- Remove a broken directory block format check from online scrub.
- Fix a bug where we could produce an unnecessarily tall data fork
btree when creating an attr fork.
- Fix scrub and readonly remounts racing.

While running a new fstest that races a readonly remount with scrub
running in repair mode, I observed the kernel tripping over debugging
assertions in the log quiesce code that were checking that the CIL was
empty. When the sysadmin runs scrub in repair mode, the scrub code
allocates real transactions (with reservations) to change things, but
doesn't increment the superblock writers count to block a readonly
remount attempt while it is running.
We don't require the userspace caller to have a writable file descriptor
to run repairs, so we have to call mnt_want_write_file to obtain freeze
protection and increment the writers count. It's ok to remove the call
to sb_start_write for the dry-run case because commit 8321ddb2fa29
removed the behavior where scrub and fsfreeze fight over the buffer LRU.

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.
Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

xchk_btree_check_minrecs() checks if the contents of the immediate child of a
bmbt root block can fit within the root block. This check could fail on inodes
with an attr fork since xfs_bmap_add_attrfork_btree() used to demote the
current root node of the data fork as the child of a newly allocated root node
if it found that the size of "struct xfs_btree_block" along with the space
required for records exceeded that of space available in the data fork.
xfs_bmap_add_attrfork_btree() should have used "struct xfs_bmdr_block" instead
of "struct xfs_btree_block" for the above mentioned space requirement
calculation. This commit disables the check for unoptimized (in terms of
disk space usage) data fork bmbt trees since there could be filesystems
in use that already have such a layout.
