Hi,

OK.    Bisected.

This is the commit where we start to see blocks of NULLs in NFS files.

e261f51f25b98c213e0b3d7f2109b117d714f69d is first bad commit

    NFS: Make nfs_updatepage() mark the page as dirty.
    
    This will ensure that we can call set_page_writeback() from within
    nfs_writepage(), which is always called with the page lock set.
