[PATCH] mempool: use mempool_create_slab_pool()

2006-03-26T16:57:00+00:00

Modify well over a dozen mempool users to call mempool_create_slab_pool()
rather than calling mempool_create() with extra arguments, saving about 30
lines of code and increasing readability.

Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

SUNRPC: Ensure rpc_call_async() always calls tk_ops->rpc_release()

2006-03-20T23:11:10+00:00

Currently this will not happen if we exit before rpc_new_task() was called.
Also fix up rpc_run_task() to do the same (for consistency).

SUNRPC: introduce per-task RPC iostats

2006-03-20T18:44:17+00:00

Account for various things that occur while an RPC task is executed.
Separate timers for RPC round trip and RPC execution time show how
long RPC requests wait in queue before being sent.  Eventually these
will be accumulated at xprt_release time in one place where they can
be viewed from userland.

Test plan:
Compile kernel with CONFIG_NFS enabled.

SUNRPC: track length of RPC wait queues

2006-03-20T18:44:15+00:00

RPC wait queue length will eventually be exported to userland via the RPC
iostats interface.

Test plan:
Compile kernel with CONFIG_NFS enabled.

[PATCH] SUNRPC: Fix potential deadlock in RPC code

2006-03-14T15:57:18+00:00

In rpc_wake_up() and rpc_wake_up_status(), it is possible for the call to
__rpc_wake_up_task() to fail if another thread happens to be calling
rpc_wake_up_task() on the same rpc_task.

Problem noticed by Bruno Faccini.

SUNRPC: switchable buffer allocation

2006-01-06T19:58:55+00:00

 Add RPC client transport switch support for replacing buffer management
 on a per-transport basis.

 In the current IPv4 socket transport implementation, RPC buffers are
 allocated as needed for each RPC message that is sent.  Some transport
 implementations may choose to use pre-allocated buffers for encoding,
 sending, receiving, and unmarshalling RPC messages, however.  For
 transports capable of direct data placement, the buffers can be carved
 out of a pre-registered area of memory rather than from a slab cache.

 Test-plan:
 Millions of fsx operations.  Performance characterization with "sio" and
 "iozone".  Use oprofile and other tools to look for significant regression
 in CPU utilization.
