freebsd-smp Digest, Vol 223, Issue 4

[Sam Xia]

Hi  Ivan,
Thank you for your response.
yes, i have read the comments.  but i am not very clear what is the
difference between "SINGLE_EXIT" and "SINGLE_BOUNDARY".
>From the comments, I guess that this routine should suspend the other
threads and only one thread can run. But from the internal implementation of
"thread_single", all other threads are waked up. I am very confused.

BR, S.Xia
