    AFS: Don't put struct file on the stack · f6d335c0

    Don't put struct file on the stack as it takes up quite a lot of space
    and violates lifetime rules for struct file.
    
    Rather than calling afs_readpage() indirectly from the directory routines by
    way of read_mapping_page(), split afs_readpage() to have afs_page_filler()
    that's given a key instead of a file and call read_cache_page(), specifying the
    new function directly.  Use it in afs_readpages() as well.
    
    Also make use of this in afs_mntpt_check_symlink() too for the same reason.
