Oops, did not test with CONFIG_BLOCK disabled. The sysrq func itself is guarded with it so imho the right fixup is to do the same thing:
diff --git a/fs/super.c b/fs/super.c index 5fa9a8d..86b5575 100644 --- a/fs/super.c +++ b/fs/super.c @@ -935,6 +935,7 @@ void emergency_remount(void) } } +#ifdef CONFIG_BLOCK static void do_thaw_all_callback(struct super_block *sb) { down_write(&sb->s_umount); @@ -968,6 +969,7 @@ void emergency_thaw_all(void) schedule_work(work); } } +#endif /* * Unnamed block devices are dummy devices used by virtual
