In motivation to abstract scsi_cmnd members and insulate
drivers/transports from scsi_cmnd internals. The last
place left was the REQUEST_SENSE sequence when done
synchronous, by drivers.
Also all these drivers would do a use_sg==0 command
invocation, preventing from doing cleanups on these
drivers/transports. So this patchset is left-overs
from Christoph's 2.6.18 cleanups.
In this patchset I have re-factored scsi_error to
make it possible for drivers to use an abstract
(easy to use, I hope) API for invoking a REQUEST_SENSE
command. The API is declared in scsi/scsi_eh.h
[patch 1/5] scsi_error: code cleanup before refactoring of scsi_send_eh_cmnd()
Move some code around and add new fixtures here. So next patch is
left a Mechanical breakup of code.
[patch 2/5] scsi_error: Refactoring scsi_error to facilitate in synchronous
REQUEST_SENSE
Here new API is introduced in scsi/scsi_eh.h and mechanical move of code
to the new functions.
[PATCH 3/5] usb: transport.c use scsi_eh API in REQUEST_SENSE execution
Use above API for drivers/usb/storage/transport.c. Now that last
User of use_sg==0, we can do the USB storage cleanups.
[PATCH 4/5] NCR5380: Use scsi_eh API for REQUEST_SENSE invocation
All NCR5380 family of drivers used to send a REQUEST_SENSE
command.
[PATCH 5/5] arm: fas216 Use scsi_eh API for REQUEST_SENSE invocation
drivers/scsi/arm/fas216.c need change also.
Please Test as much as possible, and report any problems/differences.
