sunrpc: remove sv_kill_signal field from svc_serv struct

2008-06-23T17:02:49+00:00

Since we no longer make any distinction between shutdown signals with
nfsd, then it becomes easier to just standardize on a particular signal
to use to bring it down (SIGINT, in this case).

knfsd: convert knfsd to kthread API

2008-06-23T17:02:49+00:00

This patch is rather large, but I couldn't figure out a way to break it
up that would remain bisectable. It does several things:

- change svc_thread_fn typedef to better match what kthread_create expects
- change svc_pool_map_set_cpumask to be more kthread friendly. Make it
  take a task arg and and get rid of the "oldmask"
- have svc_set_num_threads call kthread_create directly
- eliminate __svc_create_thread

SUNRPC: remove svc_create_thread()

2008-04-23T20:13:42+00:00

Now that the nfs4 callback thread uses the kthread API, there are no
more users of svc_create_thread(). Remove it.

nfsd: clean up svc_reserve_auth()

2008-02-10T23:11:16+00:00

This is a void function attempting to return the return value from
another void function, which seems harmless but extremely weird, and
apparently makes some compilers complain.

While we're there, clean up a little (e.g. the switch statement had a
minor style problem and seemed overkill as long as there's only one
case).

Thanks to Trond for noticing this.

SUNRPC: spin svc_rqst initialization to its own function

2008-02-01T21:42:15+00:00

Move the initialzation in __svc_create_thread that happens prior to
thread creation to a new function. Export the function to allow
services to have better control over the svc_rqst structs.

Also rearrange the rqstp initialization to prevent NULL pointer
dereferences in svc_exit_thread in case allocations fail.

svc: Add transport hdr size for defer/revisit

2008-02-01T21:42:13+00:00

Some transports have a header in front of the RPC header. The current
defer/revisit processing considers only the iov_len and arg_len to
determine how much to back up when saving the original request
to revisit. Add a field to the rqstp structure to save the size
of the transport header so svc_defer can correctly compute
the start of a request.

svc: Make deferral processing xprt independent

2008-02-01T21:42:12+00:00

This patch moves the transport independent sk_deferred list to the svc_xprt
structure and updates the svc_deferred_req structure to keep pointers to
svc_xprt's directly. The deferral processing code is also moved out of the
transport dependent recvfrom functions and into the generic svc_recv path.

svc: Add transport specific xpo_release function

2008-02-01T21:42:08+00:00

The svc_sock_release function releases pages allocated to a thread. For
UDP this frees the receive skb. For RDMA it will post a receive WR
and bump the client credit count.

svc: Change the svc_sock in the rqstp structure to a transport

2008-02-01T21:42:08+00:00

The rqstp structure contains a pointer to the transport for the
RPC request. This functionaly trivial patch adds an unamed union
with pointers to both svc_sock and svc_xprt. Ultimately the
union will be removed and only the rq_xprt field will remain. This
allows incrementally extracting transport independent interfaces without
one gigundo patch.
