create a writable copy of the
mbuf and alter the copy instead of the original.
A writable copy of an mbuf can be made using m_dup().
Writing to non-writable mbuf's will cause data corruption in e.g. BPF and TCP
retransmits (even in the non-SMP case).

Hi Hackers,
I'm running a 6.2-RELEASE server with a /home partition that's used to backup
a customer's data. The backups are being made during the night. Since a
couple of weeks I'm running mksnap_ffs daily to create filesystem snapshots
of the data. I've been logging the time it takes mksnap_f

Hi all,
For a work related project I'm trying to create a sort of real-time control
loop. I've written a driver for a PCI data acquisition card that features a
number of digital-to-analog and analog-to-digital converters. The goal is to
create a control loop that runs about 1 times a second

Hi All,
I'm having a problem with the snd_ich driver. Directly after loading the
snd_ich module pcm0 is detected correctly, but "vmstat -i" shows about 4
interrupts every second caused by pcm0.
The problem shows up with both custom kernels and GENERIC, with or without

Hi,

Hi,
I am writing a kernel module in which I have created a kernel thread with
kthread_create. For debugging I have added a couple of printf's in the
thread-routine. Running the module on a single-proc system works fine, but
when running it on one of my SMP machines the console freezes after a c
