Subject: [PATCH] [NTFS] Finally, move old stuff back from disk.sys to ntfs.sys
 now it can be properly reached on volume opening: - Halfplement
 NtfsUserFsRequest() and add support for IRP_MN_USER_FS_REQUEST in
 NtfsFsdFileSystemControl() - Also, use the proper FSCTL code:
 FSCTL_GET_NTFS_VOLUME_DATA which exists and is documented instead of
 FSCTL_GET_NTFS_VOLUME_DATA. Spotted by Christoph.
