From 1639431a3f57b43da1e15e9268a1d691ac01ba26 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Fri, 1 Feb 2008 14:52:30 +0000 Subject: [GFS2] Merge gfs2_alloc_meta and gfs2_alloc_data Thanks to the preceeding patches, the only difference between these two functions is their name. We can thus merge them and call the new function gfs2_alloc_block to reflect the fact that it can allocate either kind of block.
