From: Chris Mason Date: Fri, 13 Mar 2009 14:24:59 +0000 (-0400) Subject: Btrfs: don't preallocate metadata blocks during btrfs_search_slot X-Git-Tag: v2.6.30-rc1~417^2~17 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fa8cfe706f9c20067c042a064999d5825a35330;p=pandora-kernel.git Btrfs: don't preallocate metadata blocks during btrfs_search_slot In order to avoid doing expensive extent management with tree locks held, btrfs_search_slot will preallocate tree blocks for use by COW without any tree locks held. A later commit moves all of the extent allocation work for COW into a delayed update mechanism, and this preallocation will no longer be required.
