Merge branch 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull debugfs patches from Al Viro:
"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"
* 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
debugfs: Provide a file creation function that also takes an initial size
new primitive: debugfs_create_automount()
debugfs: split end_creating() into success and failure cases
debugfs: take mode-dependent parts of debugfs_get_inode() into callers
fold debugfs_mknod() into callers
fold debugfs_create() into caller
fold debugfs_mkdir() into caller
debugfs_mknod(): get rid useless arguments
fold debugfs_link() into caller
debugfs: kill __create_file()
debugfs: split the beginning and the end of __create_file() off
debugfs_{mkdir,create,link}(): get rid of redundant argument
