    Subject[PATCH 0/3] block: Deletion of checks before three function calls
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Sun, 18 Jan 2015 14:50:06 +0100

    Functions which release a system resource are occasionally documented in the way
    that they tolerate the passing of a null pointer for example. I do not see a need
    because of this fact that a function caller repeats a corresponding check.

    Markus Elfring (3):
    cciss: Deletion of an unnecessary check before the function call "put_disk"
    z2ram: Delete an unnecessary check before the function call "kfree"
    Deletion of checks before the function call "iounmap"
