Yes, I'm in the middle of rebasing and fixing that. I sent this one as it
was on the bottom of the branch and with no other dependencies. The
other bits are:
- kexec and numa syscalls, currently build testing after gcc-11 pointed out
a typo in the previous version.
- rewrite of socket/device compat ioctl handling, previous version had a
build failure and some minor checkpatch.pl issues
- overhaul of netdev ndo_do_ioctl, not strictly related but helps to prove
that the compat ioctl changes are correct and is probably a good idea
regardless, this needed a number of changes for bits I had missed the
first time around.
- a simple patch to remove the now obsolete helper functions,
needed a rebase for 5.13-rc1. If everything else gets merged for 5.14
this might be something that Andrew can pick up for sending late
in the merge window, or I'll send it for 5.15 through the asm-generic
I pushed it all for reference to
I should be able to patch-bomb everyone tomorrow unless the build bots
find more issues.
