NFS: Add attribute update barriers to NFS writebacks

Ensure that other operations that race with our write RPC calls cannot revert the file size updates that were made on the server. Signed-off-by: Trond Myklebust Tested-by: Chuck Lever

NFS: Add attribute update barriers to nfs_setattr_update_inode()

2015-03-02T04:23:05Z

Ensure that other operations which raced with our setattr RPC call cannot revert the file attribute changes that were made on the server. To do so, we artificially bump the attribute generation counter on the inode so that all calls to nfs_fattr_init() that precede ours will be dropped. The motivation for the patch came from Chuck Lever's reports of readaheads racing with truncate operations and causing the file size to be reverted.

NFSv4.1/NFSv3: Add pNFS callbacks for nfs3_(read|write|commit)_done()

2015-02-03T19:06:37Z

Enable pNFS callbacks to allow flex files to work correctly with a NFSv3-enabled data server. Signed-off-by: Trond Myklebust

NFS: Move v3 declarations out of internal.h

2014-09-12T17:49:40Z

I am generally against the "one big header file" approach, and everything in the client includes this file. Let's move all the NFS v3 declarations into a v3-only header file. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

nfs: only show Posix ACLs in listxattr if actually present

2014-07-08T18:36:08Z

The big ACL switched nfs to use generic_listxattr, which calls all existing ->list handlers. Add a custom .listxattr implementation that only lists the ACLs if they actually are present on the given inode.

nfs: merge nfs_pgio_data into _header

2014-06-24T22:47:00Z

struct nfs_pgio_data only exists as a member of nfs_pgio_header, but is passed around everywhere, because there used to be multiple _data structs per _header. Many of these functions then use the _data to find a pointer to the _header. This patch cleans this up by merging the nfs_pgio_data structure into nfs_pgio_header and passing nfs_pgio_header around instead.

NFS: Create a common pgio_rpc_prepare function

2014-05-28T22:40:28Z

The read and write paths do exactly the same thing for the rpc_prepare rpc_op. This patch combines them together into a single function. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

NFS: Create a common read and write data struct

nfs: remove ->read_pageio_init from rpc ops

2014-05-28T21:50:08Z

The read_pageio_init method is just a very convoluted way to grab the right nfs_pageio_ops vector. The vector to chose is not a choice of protocol version, but just a pNFS vs MDS I/O choice that can simply be done inside nfs_pageio_init_read based on the presence of a layout driver, and a new force_mds flag to the special case of falling back to MDS I/O on a pNFS-capable volume.
