pnfs git tree status pnfs-all-2.6.37-rc1-2010-11-03

[Benny Halevy]

After merging a fix from Trond to the new readdir(plus) implementation
I've released the rebased tree, based on 2.6.37-rc1 and pulled Jim's
fix to bl_initialize_mountpoint (now bl_set_layoutdriver) also to pnfs-all-2.6.36.

The updated tree as of today includes Fred and Andy's latest
patchsets (listed in details below) and the reset rebased on top of it
and fixed up to used the new {setup,cleanup,encode}_layout{commit,return}
layout driver API.

Note that the tree is based off of Linus' current master branch,
0143832cc96d0bf78486297aad5c8fb2c2ead02a, and not on v2.6.37-rc1,
to include some UML goodies to be in v2.6.37-rc2.

I also swapped the order in the -all branch sequence and put the server
pnfs branches on top of the client's to reflect the actual submission order.

The most useful branches are
pnfs-submit, pnfs	client only code.
pnfsd			server only code
pnfsd-all		client + server, files layout only
pnfs-all-latest		everything, serialized.
