memcg-move-charge-of-file-pages.patch:

when CONFIG_SHMFS is not enabled:

mm/shmem.c:2721: error: implicit declaration of function 'SHMEM_I'
mm/shmem.c:2721: warning: initialization makes pointer from integer without a cast
mm/shmem.c:2726: error: dereferencing pointer to incomplete type
mm/shmem.c:2727: error: implicit declaration of function 'shmem_swp_entry'
mm/shmem.c:2727: warning: assignment makes pointer from integer without a cast
mm/shmem.c:2734: error: implicit declaration of function 'shmem_swp_unmap'
mm/shmem.c:2735: error: dereferencing pointer to incomplete type


However, adding (needed)
#include <linux/spinlock.h>
to that source file does not fix the build error.

Should CGROUP_MEM_RES_CTLR depend on SHMFS or anything else?


kernel config attached.

thanks,
