SUNRPC: Fix a race in rpc_info_open

2010-09-12T23:55:25+00:00

There is a race between rpc_info_open and rpc_release_client()
in that nothing stops a process from opening the file after
the clnt->cl_kref goes to zero.

Fix this by using atomic_inc_unless_zero()...

include: replace unifdef-y with header-y

2010-08-14T20:26:51+00:00

unifdef-y and header-y has same semantic.
So there is no need to have both.

Drop the unifdef-y variant and sort all lines again

SUNRPC: Move the bound cred to struct rpc_rqst

2010-08-04T12:54:09+00:00

This will allow us to save the original generic cred in rpc_message, so
that if we migrate from one server to another, we can generate a new bound
cred without having to punt back to the NFS layer.

SUNRPC: Move remaining RPC client related task initialisation into clnt.c

2010-08-04T12:54:07+00:00

Now that rpc_run_task() is the sole entry point for RPC calls, we can move
the remaining rpc_client-related initialisation of struct rpc_task from
sched.c into clnt.c.

Also move rpc_killall_tasks() into the same file, since that too is
relative to the rpc_clnt.

SUNRPC: Ensure that rpc_exit() always wakes up a sleeping task

2010-08-04T12:54:07+00:00

Make rpc_exit() non-inline, and ensure that it always wakes up a task that
has been queued.

Kill off the now unused rpc_wake_up_task().

SUNRPC: Make the credential cache hashtable size configurable

2010-08-04T12:54:06+00:00

This patch allows the user to configure the credential cache hashtable size
using a new module parameter: auth_hashtable_size
When set, this parameter will be rounded up to the nearest power of two,
with a maximum allowed value of 1024 elements.

SUNRPC: Store the hashtable size in struct rpc_cred_cache

2010-08-04T12:54:05+00:00

Cleanup in preparation for allowing the user to determine the maximum hash
table size.
