However, it is a critical bug fix, without it the driver will likely oops from overwriting command structures, so I'd rather keep it separate from any cleanup patches.

We will have to rebase the patches we are working on anyway. Thanks for providing the fix.

I can but James has already merged the above patch to scsi-misc. So it
would be more convenient for everyone if you could rebase your
patchset on top of scsi-misc?

ACK for fixing the access to the sense buffer.
We are working internally on cleaning up the zfcp messages. With this
change, the 'trace' and 'hex dump' messages will disappear. So, could
you simply remove the ZFCP_HEX_DUMP message above, instead of fixing
it?

[PATCH] zfcp: fix sense_buffer access bug
The commit de25deb18016f66dcdede165d07654559bb332bc changed
scsi_cmnd.sense_buffer from a static array to a dynamically allocated
buffer. We can't access to sense_buffer in '&cmd->sense_buffer' way.
