reiserfs: cleanup path functions
This patch cleans up some redundancies in the reiserfs tree path code. decrement_bcount() is essentially the same function as brelse(), so we use that instead. decrement_counters_in_path() is exactly the same function as pathrelse(), so we kill that and use pathrelse() instead. There's also a bit of cleanup that makes the code a bit more readable. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
