From: Andreas Gruenbacher <agruenba@redhat.com> stable inclusion from stable-v6.6.33 commit 21d78e4c36618d34fa3f71485c11f71048abb697 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit b01189333ee91c1ae6cd96dfd1e3a3c2e69202f0 ] Commit fffe9bee14b0 ("gfs2: Delay withdraw from atomic context") switched from gfs2_withdraw() to gfs2_withdraw_delayed() in gfs2_ail_error(), but failed to then check if a delayed withdraw had occurred. Fix that by adding the missing check in __gfs2_ail_flush(), where the spin locks are already dropped and a withdraw is possible.
