X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1868f958eb56fc41c5985c8732e564a400c5fdf5;p=openwrt%2Fstaging%2Fblogic.git

sched: fix the wrong time slice value for SCHED_FIFO tasks

Function sys_sched_rr_get_interval returns wrong time slice value for
SCHED_FIFO tasks. The time slice for SCHED_FIFO tasks should be 0.
