From 22d26f9b0c3ee2ef75daf2feee8f0a9eac385939 Mon Sep 17 00:00:00 2001 From: Ye Bin Date: Mon, 30 Sep 2024 08:59:42 +0800 Subject: jbd2: remove the 'success' parameter from the jbd2_do_replay() function Keep 'success' internally to track if any error happened and then return it at the end in do_one_pass(). If jbd2_do_replay() return -ENOMEM then stop replay journal.
