I forgot to comment on that when Bruce pointed that out. My solution has been to comment out the call to vfs_msync. :-) It comes into play when you have files modified through the mmap interface (kind of rare on most systems). Obviously I have mixed feelings about vfs_msync, but I'm not suggesting here that we should get rid of it as any sort of solution. -DG David G.
