From 4fe84fb8c6b5081f7364af63aee8e118a665b966 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 10 Sep 2012 13:01:16 +0100 Subject: [PATCH] locking: Adjust spin lock inlining Kconfig options Break out the DEBUG_SPINLOCK dependency (requires moving up UNINLINE_SPIN_UNLOCK, as this was the only one in that block not depending on that option). Avoid putting values not selected into the resulting .config - they are not useful for anything, make the output less legible, and just consume space: Use "depends on" rather than directly setting the default from the combined dependency values.
