From e73b83f270828630a9ce33728f6ef61c37a82340 Mon Sep 17 00:00:00 2001 From: Bryan Schumaker Date: Thu, 24 Mar 2011 17:12:23 +0000 Subject: NFS: convert call_sync() to a function This patch changes nfs4_call_sync() from a macro into a static inline function. As a macro, the call_sync() function will not do any type checking and depends on the sequence arguments always having the same name. As a function, we get to have type checking and can rename the arguments if we so choose.
