Subject: [PATCH 00/11] y2038: add time64 syscalls
This series finally gets us to the point of having system calls with
64-bit time_t on all architectures, after a long time of incremental
preparation patches.
There was actually one conversion that I missed during the summer,
i.e. Deepa's timex series, which I now updated based the 5.0-rc1 changes
and review comments.
I hope that the actual conversion should be uncontroversial by now,
even if some of the patches are rather large.
The one area that may need a little discussion is for the system call
numbers assigned in the final patch: Can we get consensus on whether
the idea of using the same numbers on all architectures, as well as my
choice of numbers makes sense here?
So far, I have done a lot of build testing across most architectures,
which has found a number of bugs. I have also done an LTP run on arm32
with existing user space, but not on the other architectures. I did LTP
tests with a modified musl libc[2] last summer on an older version of
this series to make sure that the new 64-bit time_t interfaces work.
The version there will need updates for testing with this new kernel
patch series; I plan to do that next.
For testing, the series plus the preparatory patches is available at
[3]. Once there is a general agreement on this series and I have done
more tests for the new system calls, I plan to add this to linux-next
through my asm-generic tree or Thomas' timers tree.
Please review and test!
