From: Tao Ma Date: Mon, 3 Mar 2008 09:12:30 +0000 (+0800) Subject: ocfs2: Add ac_alloc_slot in ocfs2_alloc_context X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a4a4891164d4f6f383cc17e7c90828a7ca6a1146;p=openwrt%2Fstaging%2Fblogic.git 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.
