[git pull] debugfs stuff

[Al Viro]

	Next pile: debugfs patches, mostly to make it possible for something
like tracefs to be transparently automounted on given directory in debugfs.
New primitive in there is debugfs_create_automount(name, parent, func, arg),
which creates a directory and makes its ->d_automount() return func(arg).
Another missing primitive was debugfs_create_file_size() - open-coded in
quite a few places.  Dave's patch adds it and converts the open-code instances
to calling it.

BTW, this branch differs from what had been merged into #for-next in one
respect - I'd added my s-o-b to the last commit.  Otherwise they are
identical (i.e. the same parent and tree SHA1 in there); hopefully, merging
that one in mainline won't confuse git into conflicts for linux-next...

Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git debugfs_automount
