X-Git-Tag: v2.6.29-rc1~27^2~9^2~55^2~56^2~30^2~523 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9f3a742736cecda5a8778be70faa2f779458839f;p=pandora-kernel.git Btrfs: Do snapshot deletion in smaller chunks. Before, snapshot deletion was a single atomic unit. This caused considerable lock contention and required an unbounded amount of space. Now, the drop_progress field in the root item is used to indicate how far along snapshot deletion is, and to resume where it left off. Signed-off-by: Chris Mason --- Reading git-diff-tree failed
