    Hi all,

    There is a parameter "b_inode" in the struct "buffer_head", which I
    was under the impression; points to the inode of the file, that
    buffer/block belongs to. But when I print it, it just shows "0" Can
    anyone please tell me whats the significance of this parameter? and
    how to find which file that buffer / block belongs to?

    Also, I am under the impression that a buffer (in normal conditions)
    can be allocated to just 1 file at a time while in a page, different
    buffers in that same page can be allocated to different files. please
    correct me if I am wrong.

    Thanks and regards,

    Vineet

    p.s. I am trying to print this "b_inode" in a function
    "do_generic_file_read" in the file /mm/filemap.c
