nfs: remove unused writeverf code

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

Remove duplicate writeverf structure from merge of nfs_pgio_header and
nfs_pgio_data and remove writeverf related flags and logic to handle
more than one RPC per nfs_pgio_header.

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: rename members of nfs_pgio_data

2014-06-24T22:46:59+00:00

Rename "verf" to "writeverf" and "pages" to "page_array" to prepare for
merge of nfs_pgio_data and nfs_pgio_header.

nfs: chain calls to pg_test

2014-05-29T15:11:47+00:00

Now that pg_test can change the size of the request (by returning a non-zero
size smaller than the request), pg_test functions that call other
pg_test functions must return the minimum of the result - or 0 if any fail.

Also clean up the logic of some pg_test functions so that all checks are
for contitions where coalescing is not possible.

nfs: modify pg_test interface to return size_t

2014-05-29T15:11:43+00:00

This is a step toward allowing pg_test to inform the the
coalescing code to reduce the size of requests so they may fit in
whatever scheme the pg_test callback wants to define.

For now, just return the size of the request if there is space, or 0
if there is not.  This shouldn't change any behavior as it acts
the same as when the pg_test functions returned bool.

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.

NFSv4.1: Use layout credentials for get_deviceinfo calls

2013-06-06T20:24:37+00:00

This is not strictly needed, since get_deviceinfo is not allowed to
return NFS4ERR_ACCESS or NFS4ERR_WRONG_CRED, but lets do it anyway
for consistency with other pNFS operations.
