pnfs/objlayout: fix endianess annotation in objio_alloc_deviceid_node

2014-09-12T17:20:43+00:00

The kbuild test robot complained about a new sparse warning in
objio_alloc_deviceid_node, but it turns out that this was just a moved
reference to an existing variable.  Fix it to have the right big endian
annotated type.

Note that there are some other endianess issues in this file that I didn't
bother to sort out as they involve global headers.

pnfs: factor GETDEVICEINFO implementations

2014-09-10T19:47:03+00:00

Add support to the common pNFS core to issue GETDEVICEINFO calls on
a device ID cache miss.  The code is taken from the well debugged
file layout implementation and calls out to the layoutdriver through
a new alloc_deviceid_node method.  The calling conventions for
nfs4_find_get_deviceid are changed so that all information needed to
send a GETDEVICEINFO request is passed to the common code.

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.
