Merge tag 'xfs-fixes-6.13-rc2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs fixes from Carlos Maiolino: - Use xchg() in xlog_cil_insert_pcp_aggregate() - Fix ABBA deadlock on a race between mount and log shutdown - Fix quota softlimit incoherency on delalloc - Fix sparse inode limits on runt AG - remove unknown compat feature checks in SB write valdation - Eliminate a lockdep false positive * tag 'xfs-fixes-6.13-rc2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: don't call xfs_bmap_same_rtgroup in xfs_bmap_add_extent_hole_delay xfs: Use xchg() in xlog_cil_insert_pcp_aggregate() xfs: prevent mount and log shutdown race xfs: delalloc and quota softlimit timers are incoherent xfs: fix sparse inode limits on runt AG xfs: remove unknown compat feature check in superblock write validation xfs: eliminate lockdep false positives in xfs_attr_shortform_list
