Clean up: When naming fields and data types, follow established conventions to facilitate accurate grep/cscope searches. Additionally, for consistency, move the impl_id field into the NFSv4- specific part of the nfs_client, and free that memory in the logic that shuts down NFSv4 nfs_clients. Introduced by commit 7d2ed9ac "NFSv4: parse and display server implementation ids," Fri Feb 17, 2012.

The SETCLIENTID boot verifier is opaque to NFSv4 servers, thus there is no requirement for byte swapping before the client puts the verifier on the wire. This treatment is similar to other timestamp-based verifiers. Signed-off-by: NChuck Lever <chuck.lever@oracle.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The "struct inode *inode" was only used in a dprintk, so compiling with CONFIG_SUNRPC_DEBUG off triggers a warning. To get around this, I remove the "struct inode *inode" variable and instead change the dprintk()s to use hdr->inode instead.

We reset all I/O on a disconnected data server through the pgio layer indicated by the NFS_IOHDR_REDO flag. Differentiate between on-the-wire tasks returning with an error which must call rpc_call_done and tasks woken from the data server slot_table_waitq waiting for a session slot with a status of zero which call rpc_exit in rpc_prepare and need to skip rpc_call_done.

The "invalid layout" class of errors is handled by destroying the layout and getting a new layout from the server. Currently, the layout must be destroyed before a new layout can be obtained. This means that all references (e.g.lsegs) to the "to be destroyed" layout header must be dropped before it can be destroyed. This in turn means waiting for all in flight RPC's using the old layout as well as draining the data server session slot table wait queue. Set the NFS_LAYOUT_INVALID flag to redirect I/O to the MDS while waiting for the old layout to be destroyed.

Tasks sleeping on the slot table waitq wake to the rpc_prepare_task state. Reset the task for io through the MDS if the deviceid is invalid. The reset functions put the io pages through the pageio layer which has the advantage of re-coalescing which allows for the MDS and DS having different r/wsizes. Exit the awakened task without executing the rpc_call_done routine. Signed-off-by: NAndy Adamson <andros@netapp.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

This prevents the use of any layout for i/o that references the deviceid. I/O is redirected through the MDS.

Move the invalid deviceid test into nfs4_fl_prepare_ds, called by the filelayout read, write, and commit routines. NFS4_DEVICE_ID_NEG_ENTRY is no longer needed.

In theory, NFS v3 can have different error versions than NFS v2. v4 is already using its own nfs4_stat_to_errno() to map error codes, so rather than create something in the generic client for v2 and v3 to share I instead give v3 its own function.

I intend on creating a single nfs_fs_mount() function used by all our mount paths.
