X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a69edb55605117cc0f20aa36c49c20b96590774d;p=linux-beck.git

sched: fix update_stats_enqueue() reniced codepath

the key has to be rescaled to /weight even if it has a positive value.

(this change only affects the scheduling of reniced tasks)
