I think Archie is referring to bg fsck gaining an unfair share of cpu due to it running due to IO completions.

I have not seen any hard locks or other problems with bg fsck after your commit. -Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
