Merge tag 'xfs-6.6-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Chandan Babu:

 - Fix an integer overflow bug when processing an fsmap call

 - Fix crash due to CPU hot remove event racing with filesystem mount
   operation

 - During read-only mount, XFS does not allow the contents of the log to
   be recovered when there are one or more unrecognized rcompat features
   in the primary superblock, since the log might have intent items
   which the kernel does not know how to process

 - During recovery of log intent items, XFS now reserves log space
   sufficient for one cycle of a permanent transaction to execute.
   Otherwise, this could lead to livelocks due to non-availability of
   log space

 - On an fs which has an ondisk unlinked inode list, trying to delete a
   file or allocating an O_TMPFILE file can cause the fs to the shutdown
   if the first inode in the ondisk inode list is not present in the
   inode cache. The bug is solved by explicitly loading the first inode
   in the ondisk unlinked inode list into the inode cache if it is not
   already cached

   A similar problem arises when the uncached inode is present in the
   middle of the ondisk unlinked inode list. This second bug is
   triggered when executing operations like quotacheck and bulkstat. In
   this case, XFS now reads in the entire ondisk unlinked inode list

 - Enable LARP mode only on recent v5 filesystems

 - Fix a out of bounds memory access in scrub

 - Fix a performance bug when locating the tail of the log during
   mounting a filesystem
