From: Jan Kara Date: Thu, 6 Feb 2025 09:46:58 +0000 (+0100) Subject: jbd2: remove wrong sb->s_sequence check X-Git-Tag: v6.6.88~220 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c88f7328bb0fff66520fc9164f02b1d06e083c1b;p=thirdparty%2Fkernel%2Fstable.git jbd2: remove wrong sb->s_sequence check commit e6eff39dd0fe4190c6146069cc16d160e71d1148 upstream. Journal emptiness is not determined by sb->s_sequence == 0 but rather by sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a valid transaction ID so the check can spuriously trigger. Remove the invalid WARN_ON.
