    Subject[PATCH 1/4] sparc: bpf_jit: Use kmalloc_array() in bpf_jit_compile()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Sat, 3 Sep 2016 17:10:20 +0200

    A multiplication for the size determination of a memory allocation
    indicated that an array data structure should be processed.
    Thus use the corresponding function "kmalloc_array".

    This issue was detected by using the Coccinelle software.
