From 1c8b5b6e8b570a8038fa42cf9e7c23782bd4882c Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Fri, 13 May 2016 17:06:59 -0700 Subject: Btrfs: free sys_array eb as soon as possible While reading sys_chunk_array in superblock, btrfs creates a temporary extent buffer. Since we don't use it after finishing reading sys_chunk_array, we don't need to keep it in memory.
