Andreas Gruenbacher eb8128c5bb gfs2: Recursive gfs2_quota_hold in gfs2_iomap_end ... commit 7009fa9cd9a5262944b30eb7efb1f0561d074b68 upstream. When starting an iomap write, gfs2_quota_lock_check -> gfs2_quota_lock -> gfs2_quota_hold is called from gfs2_iomap_begin. At the end of the write, before unlocking the quotas, punch_hole -> gfs2_quota_hold can be called again in gfs2_iomap_end, which is incorrect and leads to a failed assertion. Instead, move the call to gfs2_quota_unlock before the call to punch_hole to fix that.
