}Err... But I wasn't advocating removing the locks. I was suggesting }having the routine patch in the correct locking code (or calls }thereto) based on the processor type at the first invocation of each }mutex. This way we could have a GENERIC kernel with the correct }locking code for both 3/486 and modern x86 processors compiled in }without the overhead of doing the processor type check on every call. } }Sorry if I wasn't clear.. } }Drew I am on a conference call and was also thinking about other mail. You were probably clear. Yes, this can be done. We did consider this for BSD/OS and I forgot about it. It is actually a very legitimate way to solve the problem.
