Remove select of SYSFS as requested by Greg KH. Change whitespace to tabs rather than spaces in places where it was incorrect and removed 'default m' as suggested by Adrian Bunk. Reorganised Makefile as suggested by Sam Ravnborg.

A cluster filesystem.
|
|
|
|
Allows a cluster of computers to simultaneously use a block device
|
|
that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads
|
|
and writes to the block device like a local filesystem, but also uses
|
|
a lock module to allow the computers coordinate their I/O so
|
|
filesystem consistency is maintained. One of the nifty features of
|
|
GFS is perfect consistency -- changes made to the filesystem on one
|
|
machine show up immediately on all other machines in the cluster.
|
|
|
|
To use the GFS2 filesystem, you will need to enable one or more of
|
|
the below locking modules. Documentation and utilities for GFS2 can
|
|
be found here: http://sources.redhat.com/cluster/gfs/

Single node locking module for GFS2.
|
|
|
|
Use this module if you want to use GFS2 on a single node without
|
|
its clustering features. You can still take advantage of the
|
|
large file support, and upgrade to running a full cluster later on
|
|
if required.
|
|
|
|
If you will only be using GFS2 in cluster mode, you do not need this
|
|
module.

Multiple node locking module for GFS2
|
|
|
|
Most users of GFS2 will require this module. It provides the locking
|
|
interface between GFS2 and the DLM, which is required to use GFS2
|
|
in a cluster environment.
