Like the SUBSYTEM= key we find in the environment of the uevent, this
creates a generic "subsystem" link in sysfs for every device. Userspace
usually doesn't care at all if its a "class" or a "bus" device. This
provides an unified way to determine the subsytem of a device, regardless
of the way the driver core has created it.

Allow callers to remove watches from their event handler via
inotify_remove_watch_locked(). This functionality can be used to
achieve IN_ONESHOT-like functionality for a subset of events in the
mask.

Add inotify_init_watch() so caller can use inotify_watch refcounts
before calling inotify_add_watch().
Add inotify_find_watch() to find an existing watch for an (ih,inode)
pair. This is similar to inotify_find_update_watch(), but does not
update the watch's mask if one is found.
Add inotify_rm_watch() to remove a watch via the watch pointer instead
of the watch descriptor.

The following series of patches introduces a kernel API for inotify,
making it possible for kernel modules to benefit from inotify's
mechanism for watching inodes. With these patches, inotify will
maintain for each caller a list of watches (via an embedded struct
inotify_watch), where each inotify_watch is associated with a
corresponding struct inode. The caller registers an event handler and
specifies for which filesystem events their event handler should be
called per inotify_watch.

Also, make sure dirents are marked REF_UNCHECKED when we 'discover' them
through eraseblock summary.
Signed-off-by: David Woodhouse <dwmw2@infradead.org>
Failing to do so makes the calculated length of the last node incorrect,
when we're not using eraseblock summaries.
Signed-off-by: David Woodhouse <dwmw2@infradead.org>
Especially when summary code is used, we can have in-memory data
structures referencing certain nodes without them actually being readable
on the flash. Discard the nodes gracefully in that case, rather than
triggering a BUG().

If get_user_pages() returns less pages than what we asked for, we jump
to out_unmap which will return ERR_PTR(ret). But ret can contain a
positive number just smaller than local_nr_pages, so be sure to set it
to -EFAULT always.

(!free->hdr.nused)" check in xfs_dir2_leafn_remove() fails every time and
xfs_dir2_shrink_inode() doesn't get called when it should. This causes
extra blocks to be left on an empty directory and the directory in unable
to be converted back to inline extent mode.
