Actually please don't try it!
I just tested dbench with xattrs and got 5 more different lock
inversions (brought with soft lockups ;). I just fixed all of
them with 5 more patches, I just don't have pushed them yet,
waiting for a night in my bed before writing the changelogs.
Will push/post them tomorrow.
Thanks!
