Subject: sched: do not set softirqs to nice +19
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=23bdd703a585a869f2eb32fb9f66749d0476d71e;p=openwrt%2Fstaging%2Fblogic.git

sched: do not set softirqs to nice +19

do not set softirqs to nice +19. _If_ for whatever reason
we missed to process some high-prio softirq and woke up
ksoftirqd, we should give it a fair chance to actually
get some work done, even if the system is under load.
