Hi Greg, The 4.19 branch also needs this patch. - Heming On 12/12/24 19:31, Heming Zhao wrote:
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.
