From a2c8990aed5ab000491732b07c8c4465d1b389b8 Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Tue, 24 May 2011 17:12:50 -0700 Subject: [PATCH] memsw: remove noswapaccount kernel parameter The noswapaccount parameter has been deprecated since 2.6.38 without any complaints from users so we can remove it. swapaccount=0|1 can be used instead. As we are removing the parameter we can also clean up swapaccount because it doesn't have to accept an empty string anymore (to match noswapaccount) and so we can push = into __setup macro rather than checking "=1" resp. "=0" strings Signed-off-by: Michal Hocko Cc: Hiroyuki Kamezawa Cc: Daisuke Nishimura Cc: Balbir Singh Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Documentation/kernel-parameters.txt | 3 --- mm/memcontrol.c | 13 +++---------- 2 files changed, 3 insertions(+), 13 deletions(-) diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt index 7c6624e7a5cb..5438a2d7907f 100644 --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -1777,9 +1777,6 @@ bytes respectively.
