Thanks, I've added you to EditorGroup.

There is one thing to watch on this patch for future reference (no action 
required at present).  statx always uses 64-bit timestamps, so for 32-bit 
systems __cp_stat64_statx will quietly set the timestamps to just the low 
32 bits of the timestamps provided by the kernel.  Now, this currently 
matches what the Linux kernel does for the stat syscalls on 32-bit systems 
that have them, when using a filesystem that supports timestamps outside 
the 32-bit time_t range.  But if the Linux kernel changes its handling of 
such out-of-range timestamps in future (whether producing EOVERFLOW 
errors, saturating or anything else - there has been past discussion, see 
<https://bugzilla.redhat.com/show_bug.cgi?id=1419736> and linux-fsdevel 
link therein, but I'm not sure there was any conclusion), the stat 
emulation using statx should change to match.
