The patch titled mm: align vmstat_work's timer has been removed from the -mm tree. Its filename was mm-align-vmstat_works-timer.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: align vmstat_work's timer From: Anton Blanchard <anton@xxxxxxxxx> Even though vmstat_work is marked deferrable, there are still benefits to aligning it. For certain applications we want to keep OS jitter as low as possible and aligning timers and work so they occur together can reduce their overall impact.
