[PATCHES] nfsctl fix and cleanups

[Al Viro <viro@zeniv.linux.org.uk>]

	More stuff pulled out of tree-in-dcache pile, this time nfsctl.
The first one in the series is a fix for minor bogosity, the rest -
cleanups.  Elimination of more d_alloc_name() call sites on conversions
to simple_start_creating() is what got that into preparation parts of
tree-in-dcache...

Branch in -rc5-based, lives in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #work.nfsctl
individual patches in followups.  If nobody objects, into -next it goes...

Shortlog:
      nfsctl: symlink has no business bumping link count of parent directory
      nfsd_mkdir(): switch to simple_start_creating()
      _nfsd_symlink(): switch to simple_start_creating()
      nfsdfs_create_files(): switch to simple_start_creating()
      nfsd_get_inode(): lift setting ->i_{,f}op to callers.
