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!
