From b14c55a191263889c379aeee85223bb72501824d Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Fri, 18 Aug 2017 15:15:22 -0600 Subject: [PATCH] Btrfs: remove BUG() in add_data_reference Now that we have a helper to report invalid value of extent inline ref type, we need to quit gracefully instead of throwing out a kernel panic.
