stable inclusion from stable-v6.6.33 commit d6b412c510acb6a6d4ec751a1cd0522908784e07 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 4d927b03a68846e4e791ccde6b4c274df02f11e9 ]
This function checks whether the filesystem has been been marked to be withdrawn eventually or has been withdrawn already. Rename this function to avoid confusing code like checking for gfs2_withdrawing() when gfs2_withdrawn() has already returned true.
