Message-Id: <20061013143516.15438.8802.sendpatchset@linux.site> Date: Fri, 13 Oct 2006 18:43:52 +0200 (CEST) From: Nick Piggin <npiggin@...e.de> To: Linux Memory Management <linux-mm@...ck.org> Cc: Neil Brown <neilb@...e.de>, Andrew Morton <akpm@...l.org>, Anton Altaparmakov <aia21@....ac.uk>, Chris Mason <chris.mason@...cle.com>, Linux Kernel <linux-kernel@...r.kernel.org>, Nick Piggin <npiggin@...e.de> Subject: [rfc] buffered write deadlock fix The following set of patches attempt to fix the buffered write locking problems. While looking at this deadlock, it became apparent that there are several others which are equally bad or worse. It will be very good to fix these. I ceased to become an admirer of this problem when it stopped my pagefault vs invalidate race fix from being merged! Review and comments would be very nice. Testing only if you don't value your data. I realise all filesystem developers are busy solving the 10TB fsck problem now, but if you could please take a minute to look at the fs/ changes, and also ensure your filesystem's prepare and commit_write handlers aren't broken. Sorry for the shotgun mail. It is your fault for ever being mentioned in the same email as the buffered write deadlock ;) Thanks, Nick -- SuSE Labs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
