[stgt] 0.9.11 released

[Albert Pauw]

Here's what I did:

- pulled latest git version
- added your patch
- replaced tgt-admin with the latest from Tomasz
- compiled and installed.

Made sure the proper /etc/tgt/targets.conf was setup.
Started tgt (service iscsi-target start) logged in with open-iscsi, and 
checked with tgt-admin -s:

All ok. Checked one tape drive:


lsscsi:

[root at orange tgt]# mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (41010000):
  BOT ONLINE IM_REP_EN

Also ok.

Now I used mtx -f /dev/changer status.

Result, same as seen previously, one tgtd dies off, iscsi tries to login 
again and again.

What do you want me to check more?

Albert
