From dac348e9257051e7a39224747695b53e3fc737d7 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 18 Dec 2020 14:24:25 -0500 Subject: btrfs: stop running all delayed refs during snapshot This was added in commit 361048f586f5 ("Btrfs: fix full backref problem when inserting shared block reference") to address a problem where we hit the following BUG_ON() in alloc_reserved_tree_block if (node->type == BTRFS_SHARED_BLOCK_REF_KEY) { BUG_ON(!(flags & BTRFS_BLOCK_FLAG_FULL_BACKREF)); However this BUG_ON() is bogus, and was removed by previous commit: btrfs: remove bogus BUG_ON in alloc_reserved_tree_block We no longer need to run delayed refs because of this, and can remove this flushing here.
