Subject[PATCH 5.15 056/148] xfs: fix xfs_ifree() error handling to not leak perag ref
Date
From: Brian Foster <bfoster@redhat.com>

[ Upstream commit 6f5097e3367a7c0751e165e4c15bc30511a4ba38 ]

For some reason commit 9a5280b312e2e ("xfs: reorder iunlink remove
operation in xfs_ifree") replaced a jump to the exit path in the
event of an xfs_difree() error with a direct return, which skips
releasing the perag reference acquired at the top of the function.
Restore the original code to drop the reference on error.

Fixes: 9a5280b312e2e ("xfs: reorder iunlink remove operation in xfs_ifree")
