From 6bdb72ded1e281cd8844918c39d00cdd0e59f655 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Mon, 15 Mar 2010 17:27:13 +0000 Subject: [PATCH] Btrfs: create snapshot references in same commit as snapshot This creates the reference to a new snapshot in the same commit as the snapshot itself. This avoids the need for a second commit in order for a snapshot to be persistent, and also avoids the problem of "leaking" a new snapshot tree root if the host crashes before the second commit takes place. It is not at all clear to me why it wasn't always done this way. If there is still a reason for the two-stage {create,finish}_pending_snapshots() approach I'm missing something! :) I've been running this for a couple weeks under pretty heavy usage (a few snapshots per minute) without obvious problems.
