From c5a4dd8b7c15927a8fbff83171b57cad675a79b9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 29 Mar 2007 16:47:58 -0400 Subject: SUNRPC: Eliminate side effects from rpc_malloc Currently rpc_malloc sets req->rq_buffer internally. Make this a more generic interface: return a pointer to the new buffer (or NULL) and make the caller set req->rq_buffer and req->rq_bufsize. This looks much more like kmalloc and eliminates the side effects. To fix a potential deadlock, this patch also replaces GFP_NOFS with GFP_NOWAIT in rpc_malloc. This prevents async RPCs from sleeping outside the RPC's task scheduler while allocating their buffer.
