Add support for statx(2) on Linux
This system call, new in Linux 4.11, gives us the file birth time. It's
also extensible, representing the fourth generation of stat(2) on Linux
(the original sys_stat(), sys_newstat(), sys_stat64() and now
sys_statx()), not to be confused with glibc's __xstat function, which
wraps a call to stat64. Anyway, the new one is designed to be extensible.
Now we get birth times on ext[34] on Linux too:

Modified: 2017-07-01T13:37:08.737
It's not supported in any other filesystems I have (Linux sources show
xfs has the feature too). Even on ext4, it depends on whether the
filesystem was created with 256-byte inodes, which my /boot fs wasn't.
