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
