* 5/24/00 Removed optional (and unnecessary) locking of the driver while
* the device remains plugged in. Corrected race conditions in ibmcam_open
* and ibmcam_probe() routines using this as a guideline:
- *
- * (2) The big kernel lock is automatically released when a process sleeps
- * in the kernel and is automatically reacquired on reschedule if the
- * process had the lock originally. Any code that can be compiled as
- * a module and is entered with the big kernel lock held *MUST*
- * increment the use count to activate the indirect module protection
- * before doing anything that might sleep.
- *
- * In practice, this means that all routines that live in modules and
- * are invoked under the big kernel lock should do MOD_INC_USE_COUNT
- * as their very first action. And all failure paths from that
- * routine must do MOD_DEC_USE_COUNT before returning.
