From 6af118ce51b52ceda357c671550c79628b9c4a65 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 22 Jul 2008 11:18:07 -0400 Subject: [PATCH] Btrfs: Index extent buffers in an rbtree Before, extent buffers were a temporary object, meant to map a number of pages at once and collect operations on them. But, a few extra fields have crept in, and they are also the best place to store a per-tree block lock field as well. This commit puts the extent buffers into an rbtree, and ensures a single extent buffer for each tree block. Signed-off-by: Chris Mason --- Reading git-format-patch failed
