Subject: [PATCH] sched: nohz: stop passing around unused "ticks" parameter.
References: bnc#1155798 (CPU scheduler functional and performance backports)
Patch-mainline: v5.9-rc1
Git-commit: 46132e3ac58cb2ee48051ed80bffc0070ad59b2e
The "ticks" parameter was added in commit 0f004f5a696a ("sched: Cure more
NO_HZ load average woes") since calc_global_nohz() was called and needed
the "ticks" argument.
But in commit c308b56b5398 ("sched: Fix nohz load accounting -- again!")
it became unused as the function calc_global_nohz() dropped using "ticks".
Fixes: c308b56b5398 ("sched: Fix nohz load accounting -- again!")
