Jens Axboe 50cf5f3842 io_uring/msg_ring: add an alloc cache for io_kiocb entries ... With slab accounting, allocating and freeing memory has considerable overhead. Add a basic alloc cache for the io_kiocb allocations that msg_ring needs to do. Unlike other caches, this one is used by the sender, grabbing it from the remote ring. When the remote ring gets the posted completion, it'll free it locally. Hence it is separately locked, using ctx->msg_lock. Signed-off-by: Jens Axboe <axboe@kernel.dk>		2024-06-24 08:39:55 -06:00
