2015-02-03nfs41: move file layout macros to generic pnfsPeng Tao1-10/+0
They can be reused by flexfile layout as well. Also add a code such that if read fails on one DS and there are other DSes available to use, don't resend through MDS but through pNFS so that client can read from other DSes.

2015-02-03nfs41: pull data server cache from file layout to generic pnfsPeng Tao1-19/+0
Also pull nfs4_pnfs_ds_addr and nfs4_pnfs_ds to generic pnfs. They can all be reused by flexfile layout as well. Reviewed-by: Jeff Layton <jlayton@primarydata.com> Signed-off-by: Peng Tao <tao.peng@primarydata.com> Signed-off-by: Tom Haynes <Thomas.Haynes@primarydata.com>
2015-02-03pnfs: Prepare for flexfiles by pulling out common codeTom Haynes1-11/+0
The flexfilelayout driver will share some common code with the filelayout driver. This set of changes refactors that common code out to avoid any module depenencies. Signed-off-by: Tom Haynes <loghyr@primarydata.com>
2014-09-10pnfs: factor GETDEVICEINFO implementationsChristoph Hellwig1-3/+4
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.

2014-05-29Push the file layout driver into a subdirectoryTom Haynes1-0/+156
The object and block layouts already exist in their own subdirectories. This patch completes the set! Note that as a layout denotes nfs4 already, I stripped that prefix out of the file names.
