Sorry for the delay in reviewing.

This looks good, except for the usage
of AT_STATX_DONT_SYNC when retrieving inode info.
Sure that generally doesn't change, but that
would be file system dependent, and I have seen
file systems that populate inode with counters etc.
Anyway that sort of decision would be best done
in the kernel I think, where it would have the
info whether it needs to sync for STATX_INO or not.

OK for me to push without the DONT_SYNC ?


Sure, that seems reasonable. Let me know if you need me to resend.

Pushed without AT_STATX_DONT_SYNC.
Also added the new statx.h to noinst_HEADERS,
and used our _GL_ATTRIBUTE_PURE define rather than
the less portable __attribute__.

FYI I see this is causing issues with docker images (possibly due to seccomp).

(There is a bug tracking the kernel issue but it's not publicly accessible.)

From scanning the comments it seems that once statx() is called
state is messed up, so that having ls fall back from statx() to stat()
wouldn't help in this case. So the assumption that whatever libc providing
statx() does appropriate fallback to stat() is probably still valid.

cheers,
