[0/6] mount-api: fixes and cleanups

Message

These fix issues with handling subtype (fuse specific thing) and rename
some constants on the new API to make me happy.  I realize the last patch
could be viewed as bikeshedding, but I do think suggesting falsehood in a
constant name can lead to painful real life bugs, so now is the time to
think about these issues.

Miklos Szeredi (6):
  selinux: fold superblock_doinit() into only caller
  vfs_submount: use SB_SUBMOUNT instead of MS_SUBMOUNT
  mount: fix regression in setting "subtype" from legacy API
  fsconfig: parse "subtype" param for old internal API
  fsmount: do not use legacy MS_ flags
  fsconfig: rename FSCONFIG_CMD_CREATE to FSCONFIG_CMD_OBTAIN

Hi Miklós,

I've reposted my patches with some of your changes folded in.  I will consider
the other things, but I don't have time to do that before Monday.  I think I
should also have a go at porting fuse so that we can get the subtype bits
done.

Note that I have a perl script that does some of the initial work.  It needs a
bit of fixing up, but I'll post that in a mail at some point.
