bac6024b5a
This commit adds a new mpool base module type: basic. This module can be used with an opal_free_list_t to allocate space from a pre-allocated block (such as a shared memory region). The new module only supports allocation and is not meant for more dynamic use cases at this time. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
