Looking first Linus's patch I guessed right what does it mean recursion over a sempahore (not that there would be many other choices though ;). As I just pointed out the write atomicity is not more garanteed from the internal path of the same process (previously in such case we would deadlock but sure we had no ways to corrupt things). It's still garanteed that many processes working on a critical section protected by the same semaphore will not mess up things.
