Subject: [PATCH 6/8] btrfs: use btrfs_tree_read_lock in btrfs_search_slot
Date: Fri,  6 Nov 2020 16:27:34 -0500	[thread overview]
Message-ID: <cce77fcffe84af208d0260120a874134b771ce65.1604697895.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1604697895.git.josef@toxicpanda.com>

We no longer use recursion, so
__btrfs_tree_read_lock(BTRFS_NESTING_NORMAL) == btrfs_tree_read_lock.
Replace this call with the simple helper.
