I have a query here:
My kernel version is 2.2.13, running on a RHL 6.0 system. In my
/usr/src/linux/include/asm/param.h, I find:
#ifndef HZ
#define HZ 100
#endif
And in /usr/src/linux/drivers/block/ide.h:
/*
* Timeouts for various operations:
*/
#define WAIT_DRQ (5*HZ/100) /* 50msec - spec allows up to 20ms */
With the above HZ value, that should work out to 5, not 50. Is there a factor
of 10 somewhere hidden, or is it really 5 ms?
