| Subject | [RFC PATCH 0/9] allocate sys_membarrier system call number on major archs |
| Message-ID | <q29MB-3F0-5@gated-at.bofh.it> |
Wire up the sys_membarrier system call on all major architectures. This would need testing from architecture maintainers and/or enthusiasts. Posting as RFC for now. Could be picked into Andrew's tree once we get the Tested-by tags.
