LOLLM complained that this function ignores runtime errors being
returned by xrep_iunlink_store_*. Rework the function signature so that
we can return runtime errors to abort the repair.

If we find a rogue free inode and decide to reinsert it into the
unlinked list, we need to set the prev pointer to NULLAGINO so that the
incore list gets updated.

xrep_iunlink_resolve_bucket is supposed to reconstruct as much of the
incore prev and next unlinked list pointers based on what it finds on
disk and in memory before we move on to relinking the truly lost inodes
back into the unlinked list. However, it's still vulnerable to infinite
loops that come in via the next_unlinked pointers.
Fix this problem by remembering which inodes we've already seen and
checking new agino pointers against that. If a bit is already set,
either this is a loop or the inode has nonzero link count. We'll deal
with the second case in a subsequent patch.

If an allocated inode shows up in the unlinked list, we need to get it
completely off the list. Set the corrected next/prev pointers such that
the inode will not look like it should be on an unlinked list at all.

LOLLM noticed a longstanding bug where xrep_iunlink_walk_ondisk_bucket
tries to walk ragi->sc->sa.agi_bp to rebuild the unlinked inode lists.
Unfortunately, it's possible for agi_bp to be null if the buffer

checks) instead.

LOLLM pointed out an inconsistency in the block reservation code in
xrep_rtbitmap. The first is that the reservation computation is not
consistent between the code that sets up the repair and the code that
tries to avoid exceeding the transaction reservation once we know how
big the rtbitmap really must be. As a result, the logic doesn't work.
In fixing that, a second problem emerges: if we do readjust, we ask for
the entire reservation all over again. We really only need the delta,
so ask only for that.
Fix all these problems by hoisting the computation to a trivial helper
so that it gets used in both places.

xfstests xfs/377 can make xfs_scrub repeatedly check and repair the
attr block map after inode repair zaps an attr fork.
When inode repair zaps an attr fork, it records
XFS_SICK_INO_BMBTA_ZAPPED so that scrub/repair can revisit the attr fork
block map. If the fork has been reset to an empty state and removed,
BMBTA repair has no attr fork mappings to rebuild and can return success.
The post-repair scrub then runs with XREP_ALREADY_FIXED set, which means
xchk_file_looks_zapped() deliberately ignores the stale zapped health bit
and asks xchk_bmap() to check the current attr fork. For an absent attr
fork, xchk_bmap() returns -ENOENT. Returning that error prevents
xchk_bmap_attr() from marking XFS_SICK_INO_BMBTA_ZAPPED healthy, leaving
the zapped health state behind even though there are no attr fork mappings
left to check.
Treat -ENOENT during post-repair BMBTA revalidation as a clean result for
the zapped attr fork: clear XFS_SICK_INO_BMBTA_ZAPPED and return success.
Keep the existing -ENOENT behavior for ordinary scrubs of absent attr
forks.

Fix this by rewriting the replace method to handle replacing the middle

as @got, and the subset of the mapping that we want to replace as @rep,
using @rep to store the results of the new allocation, and comparing
@rep to @got to figure out the exact transformations needed.

The xfs_imap structure is embedded into the xfs_inode, which means the
size of it directly affects the inode size. Replacing the xfs_daddr_t

available sources allows us to shrink the structure including the

As a side-effect the debugging check in xfs_imap() naturally now
converges to a stricter variant that checks that the cluster is located
inside a single AG, and not just inside the entire device.

Introduce an I_INO() wrapper as a shortcut to the inode number so that
we don't have to propagate the VFS inode everywhere.
The only non-obvious part is the clearing of i_ino to 0 for RCU freeing

xrep_cow_find_bad_rt() initializes scrub rtgroup state before the
force-rebuild path calls xrep_cow_mark_file_range(). If that call
fails, the code jumps directly to out_rtg, which skips the scrub
rtgroup cleanup and only drops the local rtgroup reference.
Remove the unnecessary jump so the function falls through to out_sr,
ensuring the realtime cursors, lock state, and sr->rtg reference are
released before returning.
