[pnfs] status of git://linux-nfs.org/~bhalevy/linux-pnfs.git 2008-04-30

[Benny Halevy]

I pushed the following patches today:

nfs41:

Mike Sager
e2e690b nfs41: fix hardcoding of minorversion
1034bae nfs41: add mount command option minorvers

Benny Halevy
090cf23 [SQUASHME] nfsd41: revert cosmetic changes to nfs4_check_openmode api

fred-spnfs:
c865437 [SQUASHME] pnfsd: sunrpc: Switch from nd->{dentry, mnt} to nd->path.{dentry, mnt}

To simplify the tree's structure I deleted the -2.6.24 branches.
To get rid of them in your cloned tree, run:
$ git branch -D `git branch | grep 2.6.24`
$ git remote prune <origin>
where <origin> is the name you had given to my tree when cloning it
(or adding it with "git remote add")

I also started moving forward towards 2.6.26 as it holds significant
patches to the nfs and rpc code.  I will finish that process after
the Connectathon to avoid unnecessary churn.

The tree's structure is therefore:
master-2.6.25
        upstream-2.6.25
                nfs41
                        pnfs
                                fred-pnfs
                                        fred-pnfs-block
                                        fred-spnfs
                                        fred-panlayout
        master
                upstream

Until Fred resends his revised patchset
fred-* are the branches you'd want to work from.

The plan is for the revised fred-pnfs to be merged into the
pnfs branch, then fred-pnfs-block will be revised as well
(to become "pnfs-block" again), and fred-spnfs and
fred-panlayout will be rebased and renamed accordingly.
