[Cluster-devel] GFS2: Some clean up patches

[Steven Whitehouse]

Originally gfs2 had a number of files of the form foo.c and ops_foo.c
but over time a number of these have disappeared leaving only one
varient or the other. To try and make things uniform (and indeed to
match the naming of files in other filesystems) I would like to
move towards dropping the ops_foo.c form in favour of the foo.c
form.

This set of patches is a first step towards that goal. It also
moves some functions which are only called from one place into
the same file as they are called from in order to make them
static.

Steve.
