From 4a26e66e7728112f0e1cd7eca3bcc430b3a221c9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 30 Oct 2008 16:58:32 +1100 Subject: [XFS] add keys_inorder and recs_inorder btree methods Add methods to check whether two keys/records are in the righ order. This replaces the xfs_btree_check_key and xfs_btree_check_rec methods. For the callers from xfs_bmap.c just opencode the bmbt-specific asserts.
