# Commit 0aabd10525326edfe5098c2ec5bfe05db7732c32 # Date 2014-11-25 10:05:29 +0100 # Author Jan Beulich <jbeulich@suse.com> # Committer Jan Beulich <jbeulich@suse.com> x86/cpuidle: don't count C1 multiple times Commit 4ca6f9f0 ("x86/cpuidle: publish new states only after fully initializing them") resulted in the state counter to be incremented for C1 despite that using a fixed table entry (and the statically initialized counter value already accounting for it and C0).
