From bdae997f44535ac4ebe1e055ffe59eeee946f453 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 1 Jul 2009 21:56:38 -0700 Subject: [PATCH] fs/notify/inotify: decrement user inotify count on close The per-user inotify_devs value is incremented each time a new file is allocated, but never decremented. This led to inotify_init failing after a limited number of calls.
