CVS commit: src/sys/rump/librump/rumpvfs



Module Name:    src
Committed By:   pooka
Date:           Tue Mar  1 10:02:11 UTC 2011

Modified Files:
        src/sys/rump/librump/rumpvfs: vm_vfs.c

Log Message:
Pass accurate protection info from ubc_uiomove() to the pager.
Fixes nfs{,ro}_fileio tests on at least sparc64 (and probably macppc
and other fat endian machines).

The problem was that nfs was fooled to thinking read() caused a
write fault because of VM_PROT_WRITE being unconditionally set and
therefore set NMODIFIED on a r/o file system.  It is absolutely
beyond me why the test worked on i386/amd64.  Incidentally, I seem
to have "misplaced" a few goats.
