[PATCH] mm, oom: OOM killer use rss size without shmem

makes the get_mm_rss() return size including SHMEM pages. The oom killer can't get free memory from SHMEM pages directly after kill victim process, it leads to mis-calculate victim points. Therefore, make new API as get_mm_rss_wo_shmem() which returns the rss value excluding SHMEM_PAGES. Signed-of

[PATCH] security: selinux: use kmem_cache for ebitmap

The allocated size for each ebitmap_node is 192byte by kzalloc(). Then, ebitmap_node size is fixed, so it's possible to use only 144byte for each object by kmem_cache_zalloc(). It can reduce some dynamic allocation size. Signed-off-by: Junil Lee --- security/selinux/ss/ebitmap.c
