See http://www.infradead.org/rpr.html Sender: linux-xfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-xfs@vger.kernel.org The ATTR_* flags have a long IRIX history, where they a userspace interface, the on-disk format and an internal interface. We've split out the on-disk interface to the XFS_ATTR_* values, but despite (or because?) of that the flag have still been a mess. Switch the internal interface to pass the on-disk XFS_ATTR_* flags for the namespace and the Linux XATTR_* flags for the actual flags instead. The ATTR_* values that are actually used are move to xfs_fs.h with a new XFS_IOC_* prefix to not conflict with the userspace version that has the same name and must have the same value.
