This patchset untangles some of the locking in reiserfs. It has seen more testing as part of the maintenance cycle in SLE 11 SP2. - We push the write lock out of the xattr code. It doesn't need it and we can simplify locking by releasing and reacquiring the locks around the xattr calls. - Handle nested locks properly. There's confusion on when a lock is nested, when it's not, and how to drop it across schedules like the BKL it is modeled after. We make the distinction between taking/releasing the lock and when to drop it for schedules and simplify the logic. This fixes a number of deadlocks that happen because the intention was to drop the write lock but it really only decremented the use count. - Fix the deadlocks with the quota code. This involves dropping the write lock before quota calls and reacquring it afterwards. Without this patch reiserfs quotas are essentially unusable.
