[PATCH 3/4] watchdog: split out config options

Split SOFTLOCKUP_DETECTOR from LOCKUP_DETECTOR, and split HARDLOCKUP_DETECTOR_PERF from HARDLOCKUP_DETECTOR. LOCKUP_DETECTOR provides the boot, sysctl, and programming interfaces for lockup detectors. An architecture that defines HAVE_NMI_WATCHDOG need not use this this if it has a very basic

[PATCH -mm 11/13] memcg, THP, swap: Make mem_cgroup_swapout() support THP

From: Huang Ying This patch makes mem_cgroup_swapout() works for the transparent huge page (THP). Which will move the memory cgroup charge from memory to swap for a THP. This will be used for the THP swap support. Where a THP may be swapped out as a whole to a set of

[PATCH -mm 10/13] memcg, THP, swap: Avoid to duplicated charge THP in swap cache

From: Huang Ying For a THP (Transparent Huge Page), tail_page->mem_cgroup is NULL. So to check whether the page is charged already, we need to check the head page. This is not an issue before because it is impossible for a THP to be in the swap cache before. But after we
