From ca19b4a69962fa850d5a22aa7a335106fcba0473 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Fri, 18 May 2018 11:00:19 +0800 Subject: Btrfs: remove superfluous free_extent_buffer in read_block_for_search read_block_for_search() can be simplified as: tmp = find_extent_buffer(); if (tmp) return; ... free_extent_buffer(); read_tree_block(); Apparently, @tmp must be NULL at this point, free_extent_buffer() is not needed.
