Since ntfs3 is a drop-in for legacy ntfs we alias legacy ntfs to ntfs3 just like ext3 is aliased to ext4. We also enforce legacy ntfs is always mounted read-only and give it custom file operations to ensure that ioctl()'s can't be abused to perform write operations. * Fix an unbalanced module_get() in bdev_open(). * Two smaller fixes for the netfs work done earlier in this cycle. * Fix the errno returned from the new FS_IOC_GETUUID and FS_IOC_GETFSSYSFSPATH ioctls. Both commands just pull information out of the superblock so there's no need to call into the actual ioctl handlers. So instead of returning ENOIOCTLCMD to indicate to fallback we just return ENOTTY directly avoiding that indirection. /* Testing */ clang: Debian clang version 16.0.6 (19) gcc: (Debian 13.2.0-7) 13.2.0 All patches are based on v6.9-rc3.
