From ea4e61c7f46d33fdf17580a925e47cc83570d658 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Sat, 23 May 2020 08:13:50 -0500 Subject: gfs2: introduce new gfs2_glock_assert_withdraw Before this patch, asserts based on glocks did not print the glock with the error. This patch introduces a new macro, gfs2_glock_assert_withdraw which first prints the glock, then takes the assert. This also changes a few glock asserts to the new macro.
