[GFS2] Replace revoke structure with bufdata structure
Both the revoke structure and the bufdata structure are quite similar. They are basically small tags which are put on lists. In addition to which the revoke structure is always allocated when there is a bufdata structure which is (or can be) freed. As such it should be possible to reduce the number of frees and allocations by using the same structure for both purposes. This patch is the first step along that path. It replaces existing uses of the revoke structure with the bufdata structure. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
