This patch updates the Documentation to reflect this change. Signed-off-by: Rodrigo Freire Acked-by: Vlastimil Babka Cc: Hugh Dickins Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mempolicy: document cpuset interaction with tmpfs mpol mount option

2010-05-25T15:06:57Z

Update Documentation/filesystems/tmpfs.txt to describe the interaction of tmpfs mount option memory policy with tasks' cpuset mems_allowed. Note: the mount(8) man page [in the util-linux-ng package] requires similiar updates.

mount -t tmpfs -o mpol=: check nodes online

2007-06-09T00:23:32Z

Randy Dunlap reports that a tmpfs, mounted with NUMA mpol= specifying an offline node, crashes as soon as data is allocated upon it. Now restrict it to online nodes, where before it restricted to MAX_NUMNODES.

[PATCH] tmpfs: recommend remount for mpol

akpm points out that switching to a non-NUMA kernel could be irritating if mounting tmpfs fails on an mpol option: tmpfs.txt recommend remount. Signed-off-by: Hugh Dickins Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] tmpfs: fix mount mpol nodelist parsing

2006-02-22T01:10:15Z

I've been dissatisfied with the mpol_nodelist mount option which was added to tmpfs earlier in -rc. Replace it by mpol=policy:nodelist. And it was broken: a nodelist is a comma-separated list of numbers and ranges; the mount options are a comma-separated list of token=values. Whoops, blindly strsep'ing on commas doesn't work so well: since we've no numeric tokens, and unlikely to add them, use that to distinguish. Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject all its options as invalid if not NUMA. /proc shows MPOL_PREFERRED as "prefer", so use that name for the policy instead of "preferred". Enforce that mpol=default has no nodelist; that mpol=prefer has one node only; that mpol=bind has a nodelist; but let mpol=interleave use node_online_map if no nodelist given.
