One level below that, you can of course choose to build
a distro with only 64-bit time_t regardless of whether there
is still support for 32-bit time_t in kernel and glibc or not.

Do you mean I could merge kernel port into linux-4.19 or linux-4.20.
But let glibc merged after linux-4.21 and csky glibc only support
time64 syscalls ?

Yes, that's what I meant. Note that it won't get merged into 4.19:
the merge window for that was after the 4.18 release and no
new features are getting merged for 4.19 that have not made it
into 4.19-rc1 already.

Getting your code into linux-next now is the prerequisite for you
sending a pull request during the 4.20 window.
