From 0ca1f7ceb1991099ed5273885ebcf4323948c72e Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Sun, 16 May 2010 10:48:47 -0400 Subject: Btrfs: Update metadata reservation for delayed allocation Introduce metadata reservation context for delayed allocation and update various related functions. This patch also introduces EXTENT_FIRST_DELALLOC control bit for set/clear_extent_bit. It tells set/clear_bit_hook whether they are processing the first extent_state with EXTENT_DELALLOC bit set. This change is important if set/clear_extent_bit involves multiple extent_state.
