    Subject[PATCH v5 2/6] staging: android: binder: fix BINDER_SET_MAX_THREADS declaration
    Date
    This change will fix the BINDER_SET_MAX_THREADS ioctl to use __u32
    instead of size_t for setting the max threads. Thus using the same
    handler for 32 and 64bit kernels.

    This value is stored internally in struct binder_proc and set to 15
    on open_binder() in the libbinder API(thus no need for a 64bit size_t
    on 64bit platforms).

    The change does not affect existing 32bit ABI.
