[Xen-devel] [PATCH] libxl: events: Do not abort remus with ERROR_TIMEOUT

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

When the timeout set for prompting the next remus iteration fires, we
should not treat the ERROR_TIMEDOUT as an error.

Bug in 31c836f4 "libxl: events: Permit timeouts to signal ao abort".
