Subject: [PATCH 00/10] timers/cpuidle: Fixes and cleanups
Date: Fri, 11 Aug 2023 19:00:39 +0200 [thread overview]
Message-ID: <20230811170049.308866-1-frederic@kernel.org> (raw)
Hi,
The first part of the series is cpuidle callback fixes against timers,
some of which haven't been Signed by Peter yet.
Another part is removing the overhead of useless TIF_NR_POLLING clearing.
The rest is comments.
