(1) it's unnecessary
(2) it causes machines to hang (yup!)
(3) it'd be gone in a few days anyway (it'd been yanked out
of 4.4-Lite by macklem long ago)
It was only there because macklem couldn't originally decide if things
should be locked, or not...
Remove comment talking about nfsiomaps that we don't have.
Always use credentials that are in the buffer header, in stead of trying
to get them from pageproc, which may once have been necessary to push pages
to swap (cannot imaging anyone having exercised this over NFS though).
John Woods, jfwfrom: @ksr.com. also, fixes the following problems:
the va_gen field is in a similar position
(Suns are going to be reporting the change-date microseconds as their
"generation"), I've supplied my own set of diffs below for your inspection.
Note these aren't even compiled, but they're pretty similar to what I had
to do to our older version of OSF/1 here. (There's also an unrelated change
supplied for xdr_subs.h; the pointer types supplied to the fxdr_time() and
txdr_time() macros are not, in fact, both struct timevals. That turns out
to be one of many tips-of-the-iceberg facing those porting the (old) Berkeley
NFS code to 64-bit machines...)
