[ltt-dev] [URCU PATCH 1/3] Rename all memory primitives with prefix cmm_

David Goulet david.goulet at polymtl.ca
Thu Nov 18 15:31:34 EST 2010


In order to not pollute the userspace namespace for application
using liburcu or any lib/apps linked with urcu, this patch if the
first of three major refactor for naming convention.

The cmm_ prefix is a short name for Concurrent Memory Model and was
suggested by Mathieu Desnoyers and Paul E. Mckenney. Every memory
primitives such as mb, wmb, rmb, and so on are renamed.
