Pages should be marked busy only for some special occasions, wired pages are not normally busy; the correct explanation is quite a bit longer than this, the comment in the code explains VPO_BUSY as "page is in transit". Right now this flag doesn't seem tom affect vboxdrv code but it may lead to surprises when some parts of code that are incorrect now are re-implemented properly: http://article.gmane.org/gmane.os.freebsd.devel.emulation/9297 > BTW you reported about the GCC 4.5 header stuff and it was also already fixed: > > http://lists.freebsd.org/pipermail/freebsd-emulation/2011-December/009312.html > Thank you! -- Andriy GaponReceived on Mon Dec 05 2011 - 12:56:53 UTC
