b0a7281646 Remove a bunch of unneeded printk lines. Also, this line: 
TRACE_DBG("Created tid '%08lX'", (unsigned long)&tr_id[4]);

is wrong. All it will do is print the address of the fifth byte in the tr_id.

It should cast to an unsigned long * and deref it, at least. However, I have
anothe change that prints out the tr_id as a SAS address.

359cdf786a Include support for PR in scst_local.c. We return a SAS-style Protocol ID. I 
use an OUI that I think is not currently in use, so it seems unlikely that we
will clash with anyone else, but you never know. I might have to change it
later.

02d6dc9860 Functional changes: 
- Changed default value for the kernel module parameter thread from 0 to 1 because mode 0 can trigger soft lockup complaints under sufficient load.
- Changed default value for the kernel module parameter srpt_autodetect_cred_req from false to true.
Non-functional changes:
- Removed several superfluous casts in ib_srpt.c.
Performance-related changes:
- Rearranged if/then/else statements such that the most frequently executed code occurs first.
- When SCST_MAX_TGT_DEV_COMMANDS > 128, the SRP receive queue size is now SCST_MAX_TGT_DEV_COMMANDS instead of 128.
Bug fixes:
- Fixed performance bug in modes thread=0 and 2.
- Fixed a bug in IB send queue overflow handling.
- Fixed race related to IB completion thread creation (mode thread=1).
- Made sure that the following warning is no longer triggered during module removal:
