Currently we queue mark into a list of marks for destruction in __fsnotify_free_mark() and keep the last mark reference dangling. After the worker waits for SRCU period, it drops the last reference to the mark which frees it. This scheme has the disadvantage that if we hold reference to a mark and drop and reacquire SRCU lock, the mark can get freed immediately which is slightly inconvenient and we will need to avoid this in the future. Move to a scheme where queueing of mark into a list of marks for destruction happens when the last reference to the mark is dropped. Also drop reference to the mark held by group list already when mark is removed from that list instead of dropping it only from the destruction worker.
