I'm not sure about the invalidation patch now. On a 1k block size
filesystem, generic/127 fails with:

    +ltp/fsx -q -l 262144 -o 65536 -S 191110531 -N 100000 -R -W fsx_std_nommap
    +collapse range: 1000 to 3000
    +do_collapse_range: fallocate: Device or resource busy

which indicates we had an invalidation failure. This is probably
exposing some other bug, but I haven't had time to look into it yet
so I don't know.

Cheers,

Dave.
