Subject: [PATCH v2 4/7] Btrfs: remove BUG() in print_extent_item
Date: Mon, 7 Aug 2017 15:55:28 -0600 [thread overview]
Message-ID: <20170807215531.12423-5-bo.li.liu@oracle.com> (raw)
In-Reply-To: <20170807215531.12423-1-bo.li.liu@oracle.com>
btrfs_print_leaf() is used in btrfs_get_extent_inline_ref_type, so
here we really want to print the invalid value of ref type instead of
causing a kernel panic.
