Ocfs2 devel - Nov 2019 - [QUESTION] deadlock during umount and quota recovery

Hi Jan,

Umount will get hang with quota recovery, as sb->s_umount will be held
in ocfs2_finish_quota_recovery(). This patch series seem to solve this
problem but they have not merged into mainline. So I wonder if they
have been tested enough?

Hi Jun,

For your information, with this patch(21158ca85b73 ("ocfs2: without 
quota support, avoid calling quota recovery")) applied which was already 
merged into mainline, given that you are not using disk quota, recovery 
hang can be workaound.

IIRC, Jan's patches somehow didn't reach completion and might cause 
side-effect.

Of course, if Jan can finish it, that would be better.
