> That raises the maximum system size to 32768 processors. hm, why is this a signed 16 bit number when the "small" version of the patch uses unsigned 8 bit values? Unsigned 16 bit integers allow up to 65536 processors...

Ticket spinlocks Posted Feb 7, 2008 13:13 UTC (Thu) by jzbiciak (✭ supporter ✭, #5246) [Link] Are there other structures that limit Linux to 32768? Perhaps that's the context of the comment. I looked at the patch and didn't see anything that really tied it to signedness, since the comparisons are all equals compares.
Processor limit Posted Feb 7, 2008 14:20 UTC (Thu) by corbet (editor, #1) [Link] That was a slip of the brain as I was running out of time to get the article done. Of course the limit is 65536; the article has been fixed. Sorry for the confusion.
