From e42e29cc442395d62f1a8963ec2dfb700ba6a5d7 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Mon, 29 Jan 2024 08:40:23 -0600 Subject: Revert "jfs: fix shift-out-of-bounds in dbJoin" This reverts commit cca974daeb6c43ea971f8ceff5a7080d7d49ee30. The added sanity check is incorrect. BUDMIN is not the wrong value and is too small.
