http://bugzilla.kernel.org/show_bug.cgi?id=14354 --- Comment #92 from Theodore Tso <tytso@xxxxxxx> 2009-10-19 21:07:37 --- Created an attachment (id=23468) --> (http://bugzilla.kernel.org/attachment.cgi?id=23468) Testing patch; ro-diff with a WARN_ON(1) Could you try this patch on top of a stock 2.6.32-rc kernel? ext4_write_inode() should not be called before the journal is set up, and I'm not able to see how this could work. Yet if the ro-diff.patch in attachment #23458 makes a difference working, then that must be what's happening. This is a variant on that patch that executes a printk and a WARN_ON(1) when if the conditional triggers; that will allow me to figure out how ext4_write_inode() is getting called early. I'm not able to replicate this on my system with this patch, but if it's working for you, then this should allow me to see what's actually happening. If we need to simply revert the change to ext4_write_inode(), I can do that, but I'd really like to see what's going on first. If in fact there is a patch where ext4_write_inode() can get called before ext4_load_journal(), which is what sets EXT4_SB(sb)->s_journal, then there's opportunities for other mischief/data corruption. -- Configure bugmail: http://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@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
