Date: Mon, 26 Jul 2010 13:59:59 GMT From: bugzilla-daemon@...zilla.kernel.org To: linux-ext4@...r.kernel.org Subject: [Bug 16312] WARNING: at fs/fs-writeback.c:1127 __mark_inode_dirty https://bugzilla.kernel.org/show_bug.cgi?id=16312 --- Comment #8 from Jan Kara <jack@...e.cz> 2010-07-26 13:59:55 --- Hmm, looking at the original report referenced, my patches need not fix this particular warning. This particular warning rather looks like a race when udisks-part-id manages to read the device (and touch it's atime) before sd_probe_async runs and registers the bdi (via add_disk()). That seems to be possible as device_add() is run before we even schedule to run sd_async_probe() in a separate thread. Jens, any idea how this should be fixed? I believe we should avoid this race because we should better have the device's queue fully set up before allowing IO to it... But I'm far from fully understanding this area... -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
