Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs/ncpfs: fix error paths and goto statements in ncp_fill_super() configfs: register_filesystem() called too early fuse: register_filesystem() called too early ubifs: too early register_filesystem() ... and the same kind of leak for mqueue procfs: fix a vfsmount longterm reference leak
