Frederic Weisbecker d663af807d kill-the-bkl/reiserfs: conditionaly release the write lock on fs_changed() ... The goal of fs_changed() is to check whether the tree changed during a schedule(). This is a BKL legacy. A recent patch added an explicit unconditional release/reacquire of the write lock around the cond_resched() called inside fs_changed. But it's wasteful to unconditionally do that, we are creating superfluous lock contention in !TIF_NEED_RESCHED case. This patch manage that by calling reiserfs_cond_resched() from fs_changed() which only releases the lock if we are going to reschedule.
