New Revision: 286130
URL: https://svnweb.freebsd.org/changeset/base/286130
Log:
Add support for uma_small_alloc and uma_small_free, and make use of these.
This is copied from the amd64 version with minor changes. These should be
merged into a single file as from a quick look there are other copies of
the same file in other parts of the tree.
