NFS: Add attribute update barriers to NFS writebacks

2015-03-02T04:23:06+00:00

Ensure that other operations that race with our write RPC calls
cannot revert the file size updates that were made on the server.

NFS: Add attribute update barriers to nfs_setattr_update_inode()

2015-03-02T04:23:05+00:00

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.

nfs: merge nfs_pgio_data into _header

2014-06-24T22:47:00+00:00

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

2014-05-28T22:40:28+00:00

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.

NFS: Create a common read and write data struct

2014-05-28T22:12:47+00:00

At this point, the only difference between nfs_read_data and
nfs_write_data is the write verifier.

nfs: remove ->read_pageio_init from rpc ops

2014-05-28T21:50:08+00:00

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.

nfs: remove synchronous rename code

Now that nfs_rename uses the async infrastructure, we can remove this.
