Hello, It seems like Sunil has fixed a similar issue against ocfs2-1.4 several years ago: https://oss.oracle.com/git/?p=ocfs2-1.4.git;a=commitdiff_plain;h=2fd250839d0f5073af8d42e97f1db74beb621674;hp=e882faf84930431524f84598caea7d4e9a9529c5 https://oss.oracle.com/git/?p=ocfs2-1.4.git;a=commitdiff_plain;h=eccff85213d4c2762f787d9e7cb1503042ba75b9;hp=edc147473ffd9c03790dc4502b893823f44a9ec4 The old bug ticket for the discussion: https://oss.oracle.com/bugzilla/show_bug.cgi?id=1235 This fix is specifically for ocfs2-1.4, but Mark once mentioned that the BUG() there can be removed if we have a good explanation for this sort of behavior, is it time to have it in mainline?
