From 8e28ef1f2fa176854f96fb0416f2aaf5516793d0 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 23 Jan 2020 19:36:21 +0100 Subject: [PATCH] gfs2: Return bool from gfs2_assert functions The gfs2_assert functions only print messages when the filesystem hasn't been withdrawn yet, and they indicate whether or not they've printed something in their return value. However, none of the callers use that information, so simply return whether or not the assert has failed. (The gfs2_assert functions are still backwards; they return false when an assertion is true.)
