This series adds support for the pNFS operations in NFS v4.1, as well as a block layout driver that can export block based filesystems that implement a few additional export operations. Support for XFS is provided in this series, but other filesystems could be added easily. The core pNFS code of course owns its heritage to the existing Linux pNFS server prototype, but except for a few bits and pieces in the XDR path nothing is left from it. The design of this new pNFS server is fairly different from the old one - while the old one implemented very little semantics in nfsd and left almost everything to filesystems my implementation implements as much as possible in common nfsd code, then dispatches to a layout driver that still is part of nfsd and only then calls into the filesystem, thus keeping it free from intimate pNFS knowledge. More details are document in the individual patch descriptions and code comments. This code is also available from: git://git.infradead.org/users/hch/pnfs.git pnfsd-for-3.20 _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
