Hi Al,
It took me way longer than I had hoped to revisit this series, see
https://lore.kernel.org/lkml/20180912150142.157913-1-arnd@arndb.de/
for the previously posted version.
I've come to the point where all conversion handlers and most
COMPATIBLE_IOCTL() entries are gone from this file, but for
now, this series only has the parts that have either been reviewed
previously, or that are simple enough to include.
The main missing piece is the SG_IO/SG_GET_REQUEST_TABLE conversion.
I'll post the patches I made for that later, as they need more
testing and review from the scsi maintainers.
I hope you can still take these for the coming merge window, unless
new problems come up.

We no longer need the rtc compat handling to be in common code, now that
all drivers are either moved to the rtc-class framework, or (rarely)
exist in drivers/char for architectures without compat mode (m68k,
alpha and ia64, respectively).
I checked the list of ioctl commands in drivers, and the ones that are
not already handled are all compatible, again with the one exception of
m68k driver, which implements RTC_PLL_GET and RTC_PLL_SET, but has no
compat mode.
Since the ioctl commands are either compatible or differ in both structure
and command code between 32-bit and 64-bit, we can merge the compat
handler into the native one and just implement the two common compat
commands (RTC_IRQP_READ, RTC_IRQP_SET) there. The result is a slight
change in behavior, as a native 64-bit process will now also handle the
32-bit commands (RTC_IRQP_SET32/RTC_IRQP_SET).
The old conversion handler also deals with RTC_EPOCH_READ and
RTC_EPOCH_SET, which are not handled in rtc-dev.c but only in a single
device driver (rtc-vr41xx), so I'm adding the compat version in the same
place. I don't expect other drivers to need those commands in the future.

Perhaps you could look at the document in this url:
http://sg.danny.cz/sg/sg_v40.html
It is work-in-progress to modernize the SCSI generic driver. It
extends ioctl(sg_fd, SG_IO, &pt_obj) to additionally accept the sg v4
interface as defined in include/uapi/linux/bsg.h . Currently only the
bsg driver uses the sg v4 interface. Since struct sg_io_v4 is all
explicitly sized integers, I'm guessing it is immune "compat" problems.
[I can see no reference to bsg nor struct sg_io_v4 in the current
fs/compat_ioctl.c file.]
Other additions described in the that document are these new ioctls:
- SG_IOSUBMIT ultimately to replace write(sg_fd, ...)
- SG_IORECEIVE to replace read(sg_fd, ...)
- SG_IOABORT abort SCSI cmd in progress; new functionality
- SG_SET_GET_EXTENDED has associated struct sg_extended_info
The first three take a pointer to a struct sg_io_hdr (v3 interface) or
a struct sg_io_v4 object. Both objects start with a 32 bit integer:
'S' identifies the v3 interface while 'Q' identifies the v4 interface.
The SG_SET_GET_EXTENDED ioctl takes a pointer to a struct
sg_extended_info object which contains explicitly sized integers so it
may also be immune from "compat" problems. The ioctls section (13) of
that document referenced above has a table showing how many "sets and
gets" are hiding in the SG_SET_GET_EXTENDED ioctl.
BTW No change is proposed for this case:
ioctl(normal_block_device, SG_IO, &sg_v3_obj)
which is handled by block/scsi_ioctl.c
This would be a good time for me to address any "compat" concerns in the
proposed sg driver update.
