Message-ID: <c28a8b5717b2ac49382067a6f0170220cb8d022b.1615472583.git.fdmanana@suse.com> (raw)
In-Reply-To: <cover.1615472583.git.fdmanana@suse.com>

From: Filipe Manana <fdmanana@suse.com>

At btrfs_tree_mod_log_free_eb() we check if we are dealing with a leaf,
and if so, return immediately and do nothing. However this check can be
removed, because after it we call tree_mod_need_log(), which returns
false when given an extent buffer that corresponds to a leaf.

So just remove the leaf check and pass the extent buffer to
tree_mod_need_log().
