:Hi,
:
:I'm getting the 'blocks of NULLs in NFS-mounted files' problem repeatably
:with last night's -current (cvsup'd at Wed Apr 14 04:02:34 BST 1999)
:running both on server and client (except that the client's kernel is 24hrs
:older than that).
:
:It happens during a kernel build on the client, so both the sources and
:objects are being accessed via NFS. During the 'generating linker set
:emulation glue for ELF' phase, a lot of the .o's turn up with blocks of
:NULLs. The rest of the world builds fine, but /usr/obj is local so there is
:little or no NFS writing going on in that case.
:
:The client is SMP but it's been doing daily builds with -j8 since that got
:sorted out, and anyway it now fails in exactly the same way whether -j is
:used or not.

I've been working on this for the last few days. I should have an
experiemental fix today. I'll post to current & hackers when it's ready.
The problem is related to the mmap fixes which went in a few days ago.
These fixes brought out yet another bug in NFS. The mmap fixes themselves
are correct.
