From ffda89a3bf3b968bdc268584c6bc1da5c173cf12 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 3 Mar 2008 17:12:09 +0800 Subject: ocfs2: Add a new parameter for ocfs2_reserve_suballoc_bits In some cases(Inode stealing from other nodes), we may not want ocfs2_reserve_suballoc_bits to allocate new groups from the global_bitmap since it may already be full. So add a new parameter for this.
