Subject: configure: ESX does not have timerfd support
X-Git-Tag: fio-3.26~59^2
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=ffaaf8ab9331668c664c0d6084a90a8a29cf3285;p=fio.git

configure: ESX does not have timerfd support

Running fio on an ESX host fails due to the lack of support for file
descriptor based notifications of timer expiration.  This change
bypasses patch 696378af added to increase timer accuracy.
