From 06bbf67244fc63c66340bd31f4b2b60d797e886e Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Fri, 21 Sep 2018 15:20:30 +0800 Subject: [PATCH] btrfs: relocation: Remove redundant tree level check Commit 581c1760415c ("btrfs: Validate child tree block's level and first key") has made tree block level check mandatory. So if tree block level doesn't match, we won't get a valid extent buffer. The extra WARN_ON() check can be removed completely.
