[Cluster-devel] [PATCH] GFS: update gfs-kernel HEAD to 2.6.20 (please review)

[Robert Peterson]

Hi Cluster Developers,

Attached is a patch for HEAD that allows it to compile and run on an
upstream kernel.  Currently, I'm using Linus' 2.6.20-rc7 kernel from git.
The biggest changes are to (1) ops_file.c regarding upstream changes to 
vfs's
aio operations, and (2) glock.c regarding upstream changes to how
workqueues work.  It also contains a couple little cleanups. 
Please review and send me comments.

Special note about the aio changes to ops_file.c:  Wendy Cheng added
some code for AIO a while back, and this patch deviates from that code
a little bit.  Namely, there was a place in function do_read_buf where the
aio path was waiting for async io to complete, and I took that out.  Let 
me know
if you think this needs to go back in.

I'd also like to hear your opinions on if/when we should make HEAD deviate
from RHEL5 and start tracking the upstream kernel rather than the RHEL5
kernel.

Regards,

Bob Peterson
