Martin K. Petersen 1c46a2cf2d block, scsi: final compat_ioctl cleanup
This series concludes the work I did for linux-5.5 on the compat_ioctl()
 cleanup, killing off fs/compat_ioctl.c and block/compat_ioctl.c by moving
 everything into drivers.
 
 Overall this would be a reduction both in complexity and line count, but
 as I'm also adding documentation the overall number of lines increases
 in the end.
 
 My plan was originally to keep the SCSI and block parts separate.
 This did not work easily because of interdependencies: I cannot
 do the final SCSI cleanup in a good way without first addressing the
 CDROM ioctls, so this is one series that I hope could be merged through
 either the block or the scsi git trees, or possibly both if you can
 pull in the same branch.
 
 The series comes in these steps:
 
 1. clean up the sg v3 interface as suggested by Linus. I have
    talked about this with Doug Gilbert as well, and he would
    rebase his sg v4 patches on top of "compat: scsi: sg: fix v3
    compat read/write interface"
 
 2. Actually moving handlers out of block/compat_ioctl.c and
    block/scsi_ioctl.c into drivers, mixed in with cleanup
    patches
 
 3. Document how to do this right. I keep getting asked about this,
    and it helps to point to some documentation file.
 
 The branch is based on another one that fixes a couple of bugs found
 during the creation of this series.
