  "message": "mempolicy: rework shmem mpol parsing and display\n\nmm/shmem.c currently contains functions to parse and display memory policy\nstrings for the tmpfs \u0027mpol\u0027 mount option.  Move this to mm/mempolicy.c with\nthe rest of the mempolicy support.  With subsequent patches, we\u0027ll be able to\nremove knowledge of the details [mode, flags, policy, ...] completely from\nshmem.c\n\n1) replace shmem_parse_mpol() in mm/shmem.c with mpol_parse_str() in\n   mm/mempolicy.c.  Rework to use the policy_types[] array [used by\n   mpol_to_str()] to look up mode by name.\n\n2) use mpol_to_str() to format policy for shmem_show_mpol().  mpol_to_str()\n   expects a pointer to a struct mempolicy, so temporarily construct one.\n   This will be replaced with a reference to a struct mempolicy in the tmpfs\n   superblock in a subsequent patch.\n\n   NOTE 1: I changed mpol_to_str() to use a colon \u0027:\u0027 rather than an equal\n   sign \u0027\u003d\u0027 as the nodemask delimiter to match mpol_parse_str() and the\n   tmpfs/shmem mpol mount option formatting that now uses mpol_to_str().  This\n   is a user visible change to numa_maps, but then the addition of the mode\n   flags already changed the display.  It makes sense to me to have the mounts\n   and numa_maps display the policy in the same format.  However, if anyone\n   objects strongly, I can pass the desired nodemask delimeter as an arg to\n   mpol_to_str().\n\n   Note 2: Like show_numa_map(), I don\u0027t check the return code from\n   mpol_to_str().  I do use a longer buffer than the one provided by\n   show_numa_map(), which seems to have sufficed so far.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
