Subject[PATCH 4.19 128/205] btrfs: tree-checker: Fix misleading group system information
4.19-stable review patch.  If anyone has any objections, please let me know.


From: Shaokun Zhang <>

commit 761333f2f50ccc887aa9957ae829300262c0d15b upstream.

block_group_err shows the group system as a decimal value with a '0x'
prefix, which is somewhat misleading.

Fix it to print hexadecimal, as was intended.

Fixes: fce466eab7ac6 ("btrfs: tree-checker: Verify block_group_item")
