    Subject[084/156] kfifo: fix KFIFO_INIT in include/linux/kfifo.h
    2.6.33-stable review patch.  If anyone has any objections, please let us know.


    From: =?UTF-8?q?David=20H=C3=A4rdeman?= <>

    commit 4c87684d32e8f95715d53039dcd2d998dc63d1eb upstream.

    include/linux/kfifo.h first defines and then undefines __kfifo_initializer
    which is used by INIT_KFIFO (which is also a macro, so building a module
    which uses INIT_KFIFO will fail).
