Re: [PATCH] fdutimensat: add an atflag parameter

[Paul Eggert]

Thanks for adding that functionality to gnulib.  I prepared a patch
to have GNU tar use it, but found one more problem.  fdutimensat
uses this signature:

fdutimensat (int dir, char const *file, int fd, [ other args ] )

whereas the similar function in GNU tar uses the following
order instead.

fdutimensat (int fd, int dir, char const *file, [ other args ] )

The GNU tar convention is clearer, since it reflects the
semantics better: try FD first, and use that if it works;
otherwise fall back on DIR+FILE.  Could we please switch to
this order, while we're changing the API anyway?  I'll do
the gnulib gruntwork if that helps.  (And I apologize for
not earlier noticing this lack of conformance to Leibniz's
principles of notation design. :-)
