From 62b2417e84ba0734d3f4f95a17e6f5f0be54d75a Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 10 Apr 2017 12:19:40 +1000 Subject: [PATCH] sunrpc: don't check for failure from mempool_alloc() When mempool_alloc() is allowed to sleep (GFP_NOIO allows sleeping) it cannot fail. So rpc_alloc_task() cannot fail, so rpc_new_task doesn't need to test for failure. Consequently rpc_new_task() cannot fail, so the callers don't need to test.
