Thanks. > It's no more trouble than you taking the time and effort to send a well- formed question in the first place. Or at least, in follow-up to my apparently inadequate response to the one-word question "comments?" before griping on a public list. In any case, I apologize for interpreting that as a request for comments on John's message, not as you apparently expected as a request for instructions on how to revert some changes. Try reverting revision 1.137 of vm/vm_mmap.c and see if this helps. The rest are changes to code that's still running under Giant. They only pave the way for removing Giant elsewhere. For example, locally I'm running the first part of vm_fault() outside of Giant, but I haven't committed that change.
