From 8e8b329e14ad2e4d747c4c4eb33c118305401aee Mon Sep 17 00:00:00 2001 From: Mark Michelson Date: Tue, 3 Dec 2013 17:07:29 +0000 Subject: Add channel locking for channel snapshot creation. This adds channel locks around calls to create channel snapshots as well as other functions which operate on a channel and then end up creating a channel snapshot. Functions that expect the channel to be locked prior to being called have had their documentation updated to indicate such. ........
