    hpet: kill BKL, add compat_ioctl · 54066a57
    Arnd Bergmann 提交于
    hpet uses the big kernel lock in its ioctl and open
    functions. Replace this with a private mutex to be
    sure. Since we're already touching the ioctl function,
    add the compat_ioctl version as well -- all commands
    except HPET_INFO are compatible and that one is easy
    to add.
