Subject: Linux-only fdatasync() in 3c13bc
Date: Tue, 6 May 2014 12:59:39 -0700	[thread overview]
Message-ID: <20140506195938.GA18213@coyotlan.Tlalpan> (raw)

[-- Attachment #1: Type: text/plain, Size: 149 bytes --]

Also, commit 3c13bc introduced a call to fdatasync() which is not
available on FreeBSD, and probably not either on MacOS at least.

Best,
