From 889f004a8c83d515f275078687f859bc0d5ede9d Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Thu, 2 Sep 2010 13:10:10 +0800 Subject: [PATCH] ocfs2: Use the right group in nfs sync check. We have added discontig block group now, and now an inode can be allocated in an discontig block group. So get it in ocfs2_get_suballoc_slot_bit. The old ocfs2_test_suballoc_bit gets group block no from the allocation inode which is wrong. Fix it by passing the right group.
