From cecfa97a4c3a665d08cdedb78dae6da7f2ff13c3 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sat, 3 May 2014 11:18:33 +0100 Subject: [PATCH] bitbake: persist_data: Avoid fsync() calls If the power were to fail, it doesn't matter to us much if the data makes it to disk or not, we'd have other problems. However an fsync() call on a multi build autobuilder is painful so lets avoid them. This is particularly true in this case if a timeout causes a reconnect during a build.
