I think I've found the general area where the problem is occuring.
It appears to some sort of weird write()/remove() interaction.
In the make install, the problem appears to only occurs when
install -s ( install and strip binary ) is used.
This causes an NFS file to be written, copied, and then removed.
I think what is going on is that the dirty bp's associated with the
file being removed are not being cleared out prior to the NFS setattr
call that removes the actual file.
Then a flushdirtyblks() call comes along and tries to vfs_bio_awrite()'s
the B_INVALID|B_DELWRI buffers.
I still can't figure out where exactly in the code the problem is
occuring, though. It's definitely related to a just-written file via
NFS getting remove()'d, and then a later flushdirtyblks() call doing
something that causes the blocks to be written out to the server ( and
thus returning a 'Stale file' error ).
