twa is giant locked in 7-Current or everywhere?

[Artem Kuchin]

Hi!

When i installed twas driver on 6.2-STABLE it said
[FAST]

i presumed that it measn that twa is giant-lock free.

Now, after installing 7-CURRENT i see

Aug 15 17:00:02 omni3 kernel: 3ware device driver for 9000 series storage controllers, version: 3.70.03.007
Aug 15 17:00:02 omni3 kernel: twa0: <3ware 9000 series Storage Controller> port 0x3000-0x30ff mem 
0x88000000-0x89ffffff,0x8a200000-0x8a200fff irq 16 at devic
Aug 15 17:00:02 omni3 kernel: twa0: [GIANT-LOCKED]
Aug 15 17:00:02 omni3 kernel: twa0: [ITHREAD]


So, it says GIANT-LOCKED and then ITHREAD.

Apparently, i have no real understaning what those words mean.
COuld anyone explain the meaning of

FAST
ITHREAD

Giant-locked is self explanatory and.. bad.

Thank you.
