From 5549f7cdf84c02939fd368d0842aa2f472bb6e98 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 7 Jul 2009 10:28:23 -0400 Subject: [PATCH] inotify: drop user watch count when a watch is removed The inotify rewrite forgot to drop the inotify watch use cound when a watch was removed. This means that a single inotify fd can only ever register a maximum of /proc/sys/fs/max_user_watches even if some of those had been freed.
