From d534d31d6a45d71de61db22090b4820afb68fddc Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 21 Oct 2021 10:01:38 +0200 Subject: fuse: check s_root when destroying sb Checking "fm" works because currently sb->s_fs_info is cleared on error paths; however, sb->s_root is what generic_shutdown_super() checks to determine whether the sb was fully initialized or not. This change will allow cleanup of sb setup error paths.
