GFS2: Update the rw flags
After Jens recent updates: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=a1f242524c3c1f5d40f1c9c343427e34d1aadd6e et al. this is a patch to bring gfs2 uptodate with the core code. Also I've managed to squash another call to ll_rw_block() along the way. There is still one part of the GFS2 I/O paths which are not correctly annotated and that is due to the sharing of the writeback code between the data and metadata address spaces. I would like to change that too, but this patch is still worth doing on its own, I think. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
