Search for a value and print information about matching locations (detailedsearch)
==================================================================================

The detailedsearch command takes most of the same arguments as the normal
search command. Unlike normal search, detailedsearch also provides
information about the found location such as the slab and slab object, or the
PID of the task for stack locations. For example::

    crash> search ffff8addd2b92700
    ffff8addd2b92c70: ffff8addd2b92700

compared to::

    crash> detailedsearch ffff8addd2b92700
    ffff8addd2b92c70: ffff8addd2b92700  slab:blkdev_queue state:alloc obj:ffff8addd2b92700 size:2496
