| Series | ocfs2: map flags directly in flags_to_o2dlm() | expand |
Looks good to me. Reviewed-by: Wengang Wang <wen.gang.wang@oracle.com<mailto:wen.gang.wang@oracle.com>> On Mar 19, 2021, at 12:24 AM, Joseph Qi <joseph.qi@linux.alibaba.com<mailto:joseph.qi@linux.alibaba.com>> wrote: Use macro map_flag() is tricky and coccicheck outputs the following warning: fs/ocfs2/stack_o2cb.c:69:5-16: Unneeded variable: "o2dlm_flags". So map flags directly in flags_to_o2dlm() to make coccicheck happy. And remove BUG_ON() here as well to simplify code since it runs well a long time.

Use macro map_flag() is tricky and coccicheck outputs the following warning: fs/ocfs2/stack_o2cb.c:69:5-16: Unneeded variable: "o2dlm_flags". So map flags directly in flags_to_o2dlm() to make coccicheck happy. And remove BUG_ON() here as well to simplify code since it runs well a long time.
