It looks like Jeff has just posted some reiserfs fixes. :-) I'd say Martin should try Jeff's pending patches before a revert or before starting a bisection. Either apply them from http://lkml.org/lkml/2009/5/17/6, or pull from git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git for-next or wait for them to appear in Linus' tree... I for one didn't test the post v2.6.30-rc5 changes to reiserfs, but I did try them _together_ with the four pending patches on a system with reiserfs root filesystem and extended attributes disabled in the config. Everything is fine here after almost a week uptime. -- Stefan Richter -=====-=-=== -=-= -==-= http://arcgraph.de/sr/
