From 6ad112bfb5af537e9e3103c807748bb4a99bbd9e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 24 Nov 2009 18:02:23 +0000 Subject: xfs: simplify xfs_buf_get / xfs_buf_read interfaces Currently the low-level buffer cache interfaces are highly confusing as we have a _flags variant of each that does actually respect the flags, and one without _flags which has a flags argument that gets ignored and overriden with a default set. Given that very few places use the default arguments get rid of the duplication and convert all callers to pass the flags explicitly. Also remove the now confusing _flags postfix.
