1. [PATCH 0/4] Fix filesystem freezing (score: 1): Author: Jan Kara <jack@xxxxxxx>; Date: Thu, 12 Jan 2012 02:20:49 +0100; Hello, filesystem freezing is currently racy and thus we can end up with dirty data on frozen filesystem (see changelog of the first patch for detailed race description and proposed fix). This patch; /archives/xfs/2012-01/msg00138.html (8,425 bytes)
2. Re: [PATCH 0/4] Fix filesystem freezing (score: 1): Author: Dave Chinner <david@xxxxxxxxxxxxx>; Date: Thu, 12 Jan 2012 13:48:41 +1100; It only fixes the dirty data race (i.e. SB_FREEZE_WRITE). The same race conditions exist for SB_FREEZE_TRANS on XFS, and so need the same fix. That race has had one previous attempt at fixing it in X; /archives/xfs/2012-01/msg00144.html (9,446 bytes)
3. Re: [PATCH 0/4] Fix filesystem freezing (score: 1): Author: Jan Kara <jack@xxxxxxx>; Date: Thu, 12 Jan 2012 12:30:31 +0100; OK, I see. I just checked ext4 to make sure and ext4 seems to get this right. Looking into Christoph's original patch it shouldn't be hard to fix it. Instead of: atomic_inc(&mp->m_active_trans); if (; /archives/xfs/2012-01/msg00148.html (11,238 bytes)

Re: [PATCH 0/4] Fix filesystem freezing (score: 1): Author: "Ted Ts'o" <tytso@xxxxxxx>; Date: Thu, 12 Jan 2012 15:48:26 -0500; This patch series looks good to me (modulo issues others have already pointed out). Acked-by: "Theodore Ts'o" <tytso@xxxxxxx> I assume you're going to send this up through Al's vfs tree? - Ted; /archives/xfs/2012-01/msg00177.html (10,717 bytes)

Re: [PATCH 0/4] Fix filesystem freezing (score: 1): Author: Dave Chinner <david@xxxxxxxxxxxxx>; Date: Fri, 13 Jan 2012 11:09:32 +1100; You're still missing the point - that this isn't an XFS specific problem or that the write problem is a ext4 specific problem. The problem is that these are freeze state transition problems - somethi; /archives/xfs/2012-01/msg00186.html (14,419 bytes)
7. Re: [PATCH 0/4] Fix filesystem freezing (score: 1): Author: Jan Kara <jack@xxxxxxx>; Date: Fri, 13 Jan 2012 12:07:59 +0100; I understand that both state transitions are currently racy. Just ext3, ext4, reiserfs, gfs2, or btrfs do not really care about SB_FREEZE_TRANS transition because they all grew their own synchronizat; /archives/xfs/2012-01/msg00195.html (15,307 bytes)
