From 8cc938fe4237e50bea4aa557ed53b06de2319d49 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 30 Oct 2008 16:58:11 +1100 Subject: [XFS] implement generic xfs_btree_get_rec Not really much reason to make it generic given that it's so small, but this is the last non-method in xfs_alloc_btree.c and xfs_ialloc_btree.c, so it makes the whole btree implementation more structured.
