I've been looking into all the ioctls used by the android framework, and i discovered some irregular definitions in the kernel headers.
In msm_audio.h: there is the following definition #define SND_SET_DEVICE _IOW(SND_IOCTL_MAGIC, 2, struct msm_device_config *) struct msm_device_config is actually not defined in the header, but instead struct msm_snd_device_config is. The rest of the ioctls make use of structures named msm_snd_..., which might mean that this was a typo. In android_pmem.h: ioctls PMEM_GET_PHYS & PMEM_GET_SIZE are defined with _IOW, while they are reading from kernel space. I haven't looked at the rest of the ioctls if they're defined properly. In msm_adsp.h: similarly ioctl ADSP_IOCTL_WRITE_COMMAND is declared using _IOR, while it is actually writing. Are these bugs, or is something else going on.
