Then I back-ported it back to the iX kernel which is a bit behind HEAD (and fixed typos in both versions, etc), where it is now at least lightly tested. I'll attach the updated patches as a series of git commits suitable for "git am" (on the github version of the FreeBSD tree); feel free to redo them in = some other form, including perhaps combining Yuri's original patch and the small subsequent fixes. The last (and large) "rewrite for clarity" section proba= bly should stay a separate patch though. --=20 You are receiving this mail because: You are the assignee for the bug.=
