[jira] Commented: (TS-35) require linux/inkaio.h to build --enable-diskinkaio

["John Plevyak (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-35?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12784892#action_12784892 ] 

John Plevyak commented on TS-35:
--------------------------------

This was a linux specific module for kevents-style events including support for disk aio.
I vaguely remember that it worked, but there was no compelling performance
difference so it was never used in production. If that is the case at Yahoo, I would say
that this option and the code should be ripped out as the linux module is surely out of
date and probably not worth reworking for an experiment.  It would also likely require
lots of support and have portability issues.
