It was > committed in r216194... This was just a MFamd64 of r204214 -- at that point i386 and amd64 had separate busdma_bounce.c files with different sets of bug fixes. I don't think I ever fixed any new bugs; I just merged fixes between the two architectures and then (once they were identical) replaced them by a single x86 file (in r216316). This particular bug fix came from gibbs. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
