From 178c4873fd06c0361d260547ce70fcdc29b74809 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sun, 12 Nov 2023 14:15:35 -0500 Subject: [PATCH] bcachefs: Fix error path in bch2_mount() This fixes a bug discovered by generic/388 where sb->s_fs_info was NULL while the superblock was still active - the error path was entirely fubar, and was trying to do something unclear and unecessary.
