config AUTOFS4_FS
	tristate "Kernel automounter version 4 support (also supports v3)"
	help
	  The automounter is a tool to automatically mount remote file systems
	  on demand. This implementation is partially kernel-based to reduce
	  overhead in the already-mounted case; this is unlike the BSD
	  automounter (amd), which is a pure user space daemon.

	  To use the automounter you need the user-space tools from
	  <ftp://ftp.kernel.org/pub/linux/daemons/autofs/v4/>; you also
	  want to answer Y to "NFS file system support", below.

	  To compile this support as a module, choose M here: the module will be
	  called autofs4.  You will need to add "alias autofs autofs4" to your
	  modules configuration file.

	  If you are not a part of a fairly large, distributed network or
	  don't have a laptop which needs to dynamically reconfigure to the
	  local network, you probably do not need an automounter, and can say
	  N here.
he finot the same way as the refcount btree and have a per-AG reservations for the possible worst case size of it, and the patch below implements that. Note that this could increase mount times with large finobt trees. In an ideal world we would have added a field for the number of finobt fields to the AGI, similar to what we did for the refcount blocks. We should do add it next time we rev the AGI or AGF format by adding new fields. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
