fanotify is only interested in event types which contain enough information
to open the original file in the context of the fanotify listener.  Since
fanotify may not want to send events if that data isn't present we pass
the data type to the should_send_event function call so fanotify can express
its lack of interest.

inotify was supposed to have a dmesg printk ratelimitor which would cause
inotify to only emit one message per boot.  The static bool was never set
so it kept firing messages.  This patch correctly limits warnings in multiple
places.

nothing uses inotify in the kernel, drop it!

Prior to 2.6.31 inotify would not reuse watch descriptors until all of
them had been used at least once.  After the rewrite inotify would reuse
watch descriptors.  The selinux utility 'restorecond' was found to have
problems when watch descriptors were reused.  This patch reverts to the
pre inotify rewrite behavior to not reuse watch descriptors.

fsnotify event initialization is done entry by entry with almost everything
set to either 0 or NULL.  Use kmem_cache_zalloc and only initialize things
that need non-zero initialization.  Also means we don't have to change
initialization entries based on the config options.

inotify_free_mark casts directly from an fsnotify_mark_entry to an

Currently fsnotify defines a static fsnotify event which is sent when a
group overflows its allotted queue length.  This patch just allocates that
event from the event cache rather than defining it statically.  There is no
known reason that the current implementation is wrong, but this makes sure the
event is initialized and created like any other.

Audit watch init and fsnotify init both use subsys_initcall() but since the
audit watch code is linked in before the fsnotify code the audit watch code
would be using the fsnotify srcu struct before it was initialized.  This
patch fixes that problem by moving audit watch init to device_initcall() so
it happens after fsnotify is ready.

This patch allows a task to add a second fsnotify mark to an inode for the

deleting audit watch rules is not currently done under audit_filter_mutex.
It was done this way because we could not hold the mutex during inotify
manipulation.  Since we are using fsnotify we don't need to do the extra
get/put pair nor do we need the private list on which to store the parents
while they are about to be freed.

fsnotify can handle mutexes to be held across all fsnotify operations since
it deals strickly in spinlocks.  This can simplify and reduce some of the
audit_filter_mutex taking and dropping.

We should use perf_sample_data_init() to initialize struct
perf_sample_data.  As explained in the description of commit dc1d628a
("perf: Provide generic perf_sample_data initialization"), it is
possible for userspace to get the kernel to dereference data.raw,
so if it is not initialized, that means that unprivileged userspace
can possibly oops the kernel.  Using perf_sample_data_init makes sure
it gets initialized to NULL.

This conversion should have been included in commit dc1d628a, but it
got missed.
