Hi, I'm having a problem with the fsync() call on the MSDOS filesystem. I have a reproductible way (using a specific application under Wine) to get it to deadlock in the msleep() call. If I disable msdos_fsync() entirely by adding a return 0 at the top, everything runs smoothly, no deadlock. Since AFAIK the problem doesn't occur with ufs fsync(), should I suppose this may have to do (and should I start looking) with the way msdosfs handles vp->v_numoutput, can it be a deadlock with some other vnode locking in the msdosfs code, or can it be an unexpected side-effet of recent SMP/KSE changes (not likely considering my machine is UP) ? Any ideas or hints welcome on where I should start looking... -- Pierre Beyssac pb@enst.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
