5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heming Zhao <heming.zhao@xxxxxxxx>
This reverts commit dfe6c5692fb5 ("ocfs2: fix the la space leak when
unmounting an ocfs2 volume").
In commit dfe6c5692fb5, the commit log "This bug has existed since the
initial OCFS2 code." is wrong. The correct introduction commit is
30dd3478c3cd ("ocfs2: correctly use ocfs2_find_next_zero_bit()").
The influence of commit dfe6c5692fb5 is that it provides a correct
fix for the latest kernel. however, it shouldn't be pushed to stable
branches. Let's use this commit to revert all branches that include
dfe6c5692fb5 and use a new fix method to fix commit 30dd3478c3cd.
