As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers. I have patches for those as well, but they need more testing or possibly a rewrite. Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- Everything in here was posted one or more times already, sending the whole series again for review, I hope to get some input on those patches that have not already been reviewed. The entire series is also part of linux-next through https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/commit/?h=y2038 Al Viro (8): fix compat handling of FICLONERANGE, FIDEDUPERANGE
