Subject: Linux-2.6.33 compat, O_DSYNC flag added
X-Git-Tag: spl-0.5.0~34
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6801b7154ccd8df47564d0f888166f3da931f3ff;p=spl

Linux-2.6.33 compat, O_DSYNC flag added

Prior to linux-2.6.33 only O_DSYNC semantics were implemented and
they used the O_SYNC flag.  As of linux-2.6.33 this behavior was
properly split in to O_SYNC and O_DSYNC respectively.
