Re: ffs/msdosfs: Flush cache when updating mount to R/O
What if somebody remounts from default options (metadata: sync, data: nosync) to fully synced (metadata: sync, data: sync) Example: # mount | grep /home /dev/sd1h on /home type ffs (local) # /sbin/mount -u -o sync /home # mount | grep /home /dev/sd1h on /home type ffs (local, synchronous) Should this flush cache?

Another crash. I should note that this kernel is build by me with patches to GENERIC (HZ from 100 to 300), pci and acpi files. Both previous reports were from official kernel builds (snapshots).

Re: Mesa has broken r300/r600 (gallium) dri DSO
I have Intel GPU, but I can answer one of yours questions. I have written this script: #!/bin/ksh echo "" > /root/whereAreLibraries.log echo "" > /root/whichFileAndWhatFunction.log find . -name "*.so*" 2>&1 1>/root/whereAreLibraries.log echo "I have ended find command Now it is time for nm and grep" ; for LIBRAR in `cat /root/whereAreLibraries.log` ; do echo "StartingPointForNewLibrary" >> /root/whichFileAndWhatFunction.log ; echo "$LIBRAR" >> /root/whichFileAndWhatFunction.log ; echo "$LIBRAR" | xargs nm | grep drisw_create_screen -C1 >> /root/whichFileAndWhatFunction.log ; echo "EndingPointForNewLibrary" >> /root/whichFileAndWhatFunction.log ; done; and after that this command: grep drisw_create_screen /root/whichFileAndWhatFunction.log -C5 gives in output: StartingPointForNewLibrary ./usr/X11R6/lib/modules/dri/r300_dri.so F dri_util.c U drisw_create_screen 000bfdf0 t driver_RenderTexture_is_safe EndingPointForNewLibrary StartingPointForNewLibrary ./usr/X11R6/lib/modules/dri/r600_dri.so F dri_util.c U drisw_create_screen 000bfdf0 t driver_RenderTexture_is_safe EndingPointForNewLibrary > Are you saying that it works for you on amd64/i386?

Re: virtualization support
Sorry for newbie question, but I am curious and this hipervisor is new thing so there is no man pages yet. I have read general classification of hypervisors on Wikipedia and there are types: Type-1 and Type-2. I have also read about KVM on cern.ch's Wiki. https://twiki.cern.ch/twiki/bin/view/Virtualization/KVM What is the type of this hipervisor: Type-1 or Type-2? Is this hypervisor more similar to "micro"-hypervisor or to monolithic hypervisor? I am interested in short answers, even if they were slightly oversimplified.
