inotify.7: BUGS: Note possible bug triggered by watch descriptor reuse
...
Watch descriptor IDs are returned by inotify_add_watch().
When calling inotify_rm_watch() an IN_IGNORE is placed on the
inotify queue pointing to the ID of the removed watch.
inotify_add_watchi() should not return a watch descriptor ID for
which events are still on the queue but should return an
unused ID.
Unfortunately, the existing Kernel code does not provide such a
guarantee.
Actually, in rare cases watch descriptor IDs are returned by
inotify_add_watch() for which events are still on the inotify
queue.
See https://bugzilla.kernel.org/show_bug.cgi?id=77111

inotify.7: munmap() does not generate inotify events
...
mmap() and msync() were already described as not leading to
inotify events. This patch adds munmap(). I created and executed
a test to verify this.
