Hi Nic,
here are some updates to tcm_loop I've done during ALUA testing.
I've implemented a 'transport_state' attribute to simulate
transport failure and added command abort callbacks.

Bug ID: 63141
Summary: Linux Kernel will shows Got wrong page in kernel log
when Linux kernel tries to send SCSI ModeSense command
with Page code 0x08 (Caching Mode Page)
There is syncronization problem between sysPD IO path and AEN path. Driver
maintains instance-pd_list[] array, which will get updated(by calling function
megasas_get_pd_list[]), whenever any of below events occurs-
MR_EVT_PD_INSERTED
MR_EVT_PD_REMOVED
MR_EVT_CTRL_HOST_BUS_SCAN_REQUESTED
Casting (void *) value returned by kmalloc is useless
as mentioned in Documentation/CodingStyle, Chap 14.
