The patch titled sd-sched: (micro-optimisation) remove redundant assignment in recalc_task_prio() has been added to the -mm tree. Its filename is sched-implement-staircase-deadline-cpu-scheduler-tweak.patch *** Remember to use Documentation/SubmitChecklist when testing your code *** See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this ------------------------------------------------------ Subject: sd-sched: (micro-optimisation) remove redundant assignment in recalc_task_prio() From: Dmitry Adamushko <dmitry.adamushko@xxxxxxxxx> Remove redundant "p->array = array" assignment at the end of recalc_task_prio(). All the code pathes have already configured p->array accordingly by this moment.
