From 0b4d51b02a2e941beec6f02a6c7a32c5a28c5b43 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 1 Feb 2013 16:39:32 -0800 Subject: [PATCH] sunrpc: Use uid_eq and gid_eq where appropriate When comparing uids use uid_eq instead of ==. When comparing gids use gid_eq instead of ==. And unfortunate cost of type safety. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W.
