From f9615fe3113f1067093f7f68d46d281b4c9a5978 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Tue, 5 May 2020 11:50:24 -0500 Subject: [PATCH] gfs2: Change BUG_ON to an assert_withdraw in gfs2_quota_change Before this patch, gfs2_quota_change() would BUG_ON if the qa_ref counter was not a positive number. This patch changes it to be a withdraw instead. That way we can debug things more easily.
