Subject: [PATCH] SMB3: Backup intent flag missing from compounded ops
Git-commit: 4d5bdf28690a304e089ce750efc8b7dd718945c7
Patch-mainline: v4.20-rc1
References: bsc#1144333

When "backup intent" is requested on the mount (e.g. backupuid or
backupgid mount options), the corresponding flag was missing from
some of the new compounding operations as well (now that
open_query_close is gone).

Related to kernel bugzilla #200953
