From 4d5db3f536ae3886ac86877742e6f8ce69a5de06 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 19 Nov 2014 07:51:20 -0500 Subject: sunrpc: convert sp_task_pending flag to use atomic bitops In a later patch, we'll want to be able to handle this flag without holding the sp_lock. Change this field to an unsigned long flags field, and declare a new flag in it that can be managed with atomic bitops. Signed-off-by: Jeff Layton Signed-off-by: J.
