    x86: Remove BKL from apm_32 · 05d86412
    Thomas Gleixner 提交于
    The lock/unlock kernel pair in do_open() got there with the BKL push
    down and protects nothing. Remove it.
    
    Replace the lock/unlock kernel in the ioctl code with a mutex to
    protect standbys_pending and suspends_pending.
