Subject: ttm/pool: drop numa specific pools
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c21066ef697bbecc49dd7888bf8f4e7c684a8ef9;p=thirdparty%2Fkernel%2Flinux.git

ttm/pool: drop numa specific pools

The list_lru will now handle numa for us, so no need to keep
separate pool types for it. Just consolidate into the global ones.

This adds a debugfs change to avoid dumping non-existant orders due
to this change.
