Hi,
I am trying to find out where in the kernel code blocks on disk are freed.
I want to track all the blocks freed on the disk as a result of file
deletes etc., in my pseudo disk driver.
Is there an equivalent of a blockfree() or something in the 4.x kernel
code, where I can put a hook into
Hi,
I would like to set up and run the specfs benchmark on a BSD 4.10 machine.
I have been searching around for a while on how to do it, but no luck so
far. Could anybody please point me to where I can get the source code,
build/install, and configure the system so that I can profile
Hi,
I was wondering why the limit for file system snapshots in BSD 5 has been
set to 20. Is it a limitation due to the way this feature has been
implemented?

Hi,
I am referring to the message when the code in kern_shutdown.c in bsd

My understanding is that this message tells us that 1 buffer from the
buffer cache

Hi all,
Is there a system call to get all the mount points? In a user app, I guess
I would probably parse the /etc/fstab, but how do I do it in the kernel?
TIA,

Hi all,
I am responding to a post back in Oct 2003 when the checkpointing feature
was announced for DragonFly. I have been doing some research on this, and
have seen some projects that use Xen VMM to achieve checkpoints of guest
OSes.
So I was looking for inputs from people as to what everyone
a process pipeline can be made to work, but some work would need
to be done on pipes. The list goes on.

Hi,
I have a pseudo disk driver that does a copy on write to a log device.
I want to disable further retries to write if the disk space on the log
device is full. I have inserted the following code into the strategy routine
For this I have set the error code and also set the resid to zero,
Hi,
I am writing this pseudo disk driver for disk checkpointing, which
intercepts write requests to the disk (ad0s1) and performs a copy on write
of the old contents to another partition (ad0s4) before writing out the
new contents. So the driver (called shd) is mounted as
