[PATCH 00/28] SCSI EH argument reshuffle part I

[Hannes Reinecke <hare@suse.de>]

Hi all,
finally here's the patchset to revamp the SCSI EH callback arguments
which I promised to do (some years ago ...).

The overall idea is to match the scope of the eh_XXX callbacks with
the appropriate argument, eg eh_device_reset_handler() should have a
scsi device as argument etc.
Relying on the scsi command has the problem that
a) we're holding a reference on that command for the entire lifetime
of the error handling and
b) it leads to some 'interesting' driver implementations; some
higher-level EH callback implementations go through the list of
outstanding commands and try to abort this particular command only;
makes one wonder what'll happen to the other commands ...

However, this patchset has the nice side-effect that we don't need to
allocate an out-of-order scsi command in scsi_ioctl_reset(), but can
call the function directly.

As per request from hch the patchset has been split in two parts;
this is the first part which just does a general EH function cleanup
without introducing any functional differences.

As usual, comments and reviews are welcome.
