Subject: [RFC GIT PULL] timer subsystem fix/improvement

Message-ID: <aaQETUxfKRWjno5s@gmail.com> (raw)

Linus,

Please pull the latest timers/urgent Git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-urgent-2026-03-01

for you to fetch changes up to b777b5e09eabeefc6ba80f4296366a4742701103:

# MERGE NOTE: marked as RFC, as it's not a regression fix.

Improve the inlining of jiffies_to_msecs() and jiffies_to_usecs(),
for the common HZ=100, 250 or 1000 cases, only inlining them
for odd HZ values like HZ=300.

The inlining overhead showed up in performance tests of the TCP code.

(Marked as an RFC pull request, as it's not a regression.)

 Thanks,

	Ingo
