Subject: xfs: handle racing deletions in xfs_zone_gc_iter_irec
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=bc95fa240a1b8ae64d3dabe87cbe103b912afc45;p=thirdparty%2Fkernel%2Flinux.git

xfs: handle racing deletions in xfs_zone_gc_iter_irec

Under heavy garbage collection pressure from RocksDB workloads,
filesystem shutdowns can occur in xfs_zone_gc_iter_irec when
xfs_iget() returns -EINVAL for deleted files.

Fix this by handling -EINVAL just like we handle -ENOENT, allowing
zone GC to safely ignore stale mappings.
