[Xen-devel] [PATCH] linux/evtchn: Add memory barriers to evtchn ring accesses.
Xenstore infrequently hangs up on IA64. Actually the xenstored is still alive but no response from xenstore-XXX commands. After tracking down, I''ve found that evtchn_read() infrequently returns a wrong evtchn port number and evtchn_write() never unmask the exact port. This patch fixes it.
