112 mm/shmem.c.
114 But brief explanation of the behavior of memcg around shmem will be
119 - radix-tree of shmem's inode.
126 - A new page is added to shmem's radix-tree.
167 Historically, memcg's shmem handling was poor and we saw some amount
168 of troubles here. This is because shmem is page-cache but can be
169 SwapCache. Test with shmem/tmpfs is always good test.
