    You don't need to do a NFS compilation to trigger it. just to a "find"
    on a huge NFS-mounted tree and you will see it.

    Another candidate for cond_resched() is the loop in nfs_readdir(). It
    seems safe to do so be cause it calls readdir_search_pagecache() which
    would call schedule().
