From a4a4891164d4f6f383cc17e7c90828a7ca6a1146 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 3 Mar 2008 17:12:30 +0800 Subject: ocfs2: Add ac_alloc_slot in ocfs2_alloc_context In inode stealing, we no longer restrict the allocation to happen in the local node. So it is neccessary for us to add a new member in ocfs2_alloc_context to indicate which slot we are using for allocation. We also modify the process of local alloc so that this member can be used there also.
