Kernel 6.6.8 ocfs2 mount hangs on boot. (ocfs2 on kernel 6.6.5 works fine)

Using the last few kernel versions, ocfs2 ran sporadically only.
It seems that ocfs2 is tested rarely.

Comment 1 debug 2024-03-10 04:27:07 UTC

The OCFS2 mount problem was fixed with kernel 6.7.7 or 6.7.8.
OCFS2 works correctly with kernel 6.7.9 too.
