Subject: perf sched: Move struct perf_sched definition out of cmd_sched()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f36f83f947ede547833e462696893f866df77324;p=openwrt%2Fstaging%2Fblogic.git

perf sched: Move struct perf_sched definition out of cmd_sched()

For some reason it consumed quite amount of compile time when declared
as local variable, and it disappeared when moved out of the function.
Moving other variables/tables didn't help.

On my system this single-file-change build time reduced from 11s to 3s.
