I forgot to mention that this series include new udev rules. You need
to activate them using:
# udevadm control --reload-rules && udevadm trigger
(or reboot)
You also need to adopt your current drive configuration to use the new
devices ...

This is a userspace drive implementation using SG_IO.
Why we do not use the Linux tape driver anymore, because:
- missing features (MAM, Encryption, ...)
- strange permission handling - only root (or CAP_SYS_RAWIO) can
do SG_IO (SYS_RAW_IO)
- unability to detect EOT (you just get EIO)
Dietmar Maurer (11):
tape: introduce trait BlockRead
tape: introduce trait BlockWrite
tape: implement LTO userspace driver
tape: implement format/erase
tape: fix LEOM handling
tape: make fsf/bsf driver specific
tape: make sure there is a filemark at the end of the tape
sgutils2: add scsi_mode_sense helper
tape: correctly set/display drive option
tape: pmt - re-implement fsr/bsr
tape: pmt - re-implement lock/unlock command
