# 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
