NFSv4.1: Convert pNFS deviceid to use kfree_rcu()

2015-03-27T16:32:24+00:00

Use of synchronize_rcu() when unmounting and potentially freeing a lot of deviceids is problematic. There really is no reason why we can't just use kfree_rcu() here. Signed-off-by: Trond Myklebust

nfs41: pull nfs4_ds_connect from file layout to generic pnfs

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 Signed-off-by: Peng Tao Signed-off-by: Tom Haynes

pnfs: Prepare for flexfiles by pulling out common code

2015-02-03T19:06:31+00:00

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

NFS: Deletion of unnecessary checks before the function call "nfs_put_client"

2014-11-25T01:07:27+00:00

The nfs_put_client() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Trond Myklebust

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.
