Message-ID: <522554D6.4070000@oracle.com> Date: Tue, 03 Sep 2013 11:17:42 +0800 From: Jeff Liu <jeff.liu@...cle.com> To: richard -rw- weinberger <richard.weinberger@...il.com> CC: "ocfs2-users@....oracle.com" <ocfs2-users@....oracle.com>, linux-fsdevel <linux-fsdevel@...r.kernel.org>, LKML <linux-kernel@...r.kernel.org>, Sunil Mushran <sunil.mushran@...il.com>, Mark Fasheh <mfasheh@...e.com> Subject: Re: OCFS2: ocfs2_read_blocks:285 ERROR: block 532737 had the JBD bit set while I was in lock_buffer! 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?
