Merge tag 'xfs-6.3-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull moar xfs updates from Darrick Wong: "This contains a fix for a deadlock in the allocator. It continues the slow march towards being able to offline AGs, and it refactors the interface to the xfs allocator to be less indirection happy. Summary: - Fix a deadlock in the free space allocator due to the AG-walking algorithm forgetting to follow AG-order locking rules - Make the inode allocator prefer existing free inodes instead of failing to allocate new inode chunks when free space is low - Set minleft correctly when setting allocator parameters for bmap changes - Fix uninitialized variable access in the getfsmap code - Make a distinction between active and passive per-AG structure references. For now, active references are taken to perform some work in an AG on behalf of a high level operation; passive references are used by lower level code to finish operations started by other threads. Eventually this will become part of online shrink - Split out all the different allocator strategies into separate functions to move us away from design antipattern of filling out a huge structure for various differentish things and issuing a single function multiplexing call - Various cleanups in the filestreams allocator code, which we might very well want to deprecate instead of continuing - Fix a bug with the agi rotor code that was introduced earlier in this series" * tag 'xfs-6.3-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (44 commits) xfs: restore old agirotor behavior xfs: fix uninitialized variable access xfs: refactor the filestreams allocator pick functions xfs: return a referenced perag from filestreams allocator xfs: pass perag to filestreams tracing xfs: use for_each_perag_wrap in xfs_filestream_pick_ag xfs: track an active perag reference in filestreams xfs: factor out MRU hit case in xfs_filestream_select_ag xfs: remove xfs_filestream_select_ag() longest extent check xfs: merge new filestream AG selection into xfs_filestream_select_ag() xfs: merge filestream AG lookup into xfs_filestream_select_ag() xfs: move xfs_bmap_btalloc_filestreams() to xfs_filestreams.c xfs: use xfs_bmap_longest_free_extent() in filestreams xfs: get rid of notinit from xfs_bmap_longest_free_extent xfs: factor out filestreams from xfs_bmap_btalloc_nullfb xfs: convert trim to use for_each_perag_range xfs: convert xfs_alloc_vextent_iterate_ags() to use perag walker xfs: move the minimum agno checks into xfs_alloc_vextent_check_args xfs: fold xfs_alloc_ag_vextent() into callers xfs: move allocation accounting to xfs_alloc_vextent_set_fsbno() ...
