Dmemcg_test.rst111 The best way to understand shmem's page state transition is to read
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.
158 Historically, memcg's shmem handling was poor and we saw some amount
159 of troubles here. This is because shmem is page-cache but can be
160 SwapCache. Test with shmem/tmpfs is always good test.
