Revision 3670e7e12e582c6d67761275d148171feb7a9004 authored by Alexandre Bounine on 21 August 2012, 23:16:11 UTC, committed by Linus Torvalds on 21 August 2012, 23:45:03 UTC
Make sure that there is no doorbell messages left behind due to disabled interrupts during inbound doorbell processing. The most common case for this bug is loss of rionet JOIN messages in systems with three or more rionet participants and MSI or MSI-X enabled. As result, requests for packet transfers may finish with "destination unreachable" error message. This patch is applicable to kernel versions starting from v3.2.
