	depends on BLOCK
	help
	  SCO, Xenix and Coherent are commercial Unix systems for Intel
	  machines, and Version 7 was used on the DEC PDP-11. Saying Y
	  here would allow you to read from their floppies and hard disk
	  partitions.

	  If you have floppies or hard disk partitions like that, it is likely
	  that they contain binaries from those other Unix systems; in order
	  to run these binaries, you will want to install linux-abi which is
	  a set of kernel modules that lets you run SCO, Xenix, Wyse,
	  UnixWare, Dell Unix and System V programs under Linux.  It is
	  available via FTP (user: ftp) from
	  <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
	  NOTE: that will work only for binaries from Intel-based systems;
	  PDP ones will have to wait until somebody ports Linux to -11 ;-)

	  If you only intend to mount files from some other Unix over the
	  network using NFS, you don't need the System V file system support
	  (but you need NFS file system support obviously).

	  Note that this option is generally not needed for floppies, since a
	  good portable way to transport files and directories between unixes
	  (and even other operating systems) is given by the tar program ("man
	  tar" or preferably "info tar").  Note also that this option has
	  nothing whatsoever to do with the option "System V IPC". Read about
	  the System V file system in
	  <file:Documentation/filesystems/sysv-fs.txt>.
	  Saying Y here will enlarge your kernel by about 27 KB.

	  To compile this as a module, choose M here: the module will be called
	  sysv.

	  If you haven't heard about all of this before, it's safe to say N.

<div class='commit-subject'>cgroup: don't online subsystems before cgroup_name/path() are operational</div><div class='commit-msg'>While refactoring cgroup creation, a5bca2152036 ("cgroup: factor out
cgroup_create() out of cgroup_mkdir()") incorrectly onlined subsystems
before the new cgroup is associated with it kernfs_node.  This is fine
for cgroup proper but cgroup_name/path() depend on the associated
kernfs_node and if a subsystem makes the new cgroup_subsys_state
visible, which they're allowed to after onlining, it can lead to NULL
dereference.

The current code performs cgroup creation and subsystem onlining in
cgroup_create() and cgroup_mkdir() makes the cgroup and subsystems
visible afterwards.  There's no reason to online the subsystems early
and we can simply drop cgroup_apply_control_enable() call from
cgroup_create() so that the subsystems are onlined and made visible at
the same time.
