Hi People...
got a following "dead of alive" question:
how to find a root block on a ReiserFS partition
with a corrupted superblock?
reiserfsprogs-3.x.0.9j simply writes -2^32
there at start (reset_super_block) and then simply
crashes when attempting to access to such mad

Can anybody tell me, How can I create dynamic threads at Kernel level??
If u have any sample code in which Semaphore, threads, events are
implemented, Pls send.
Waiting for ur response.

Hi,
I'm working on an embedded system here which has no harddisk.
So, I can't swap to disk and need to have /var & /tmp in RAM.
I'm confused between the various options for in RAM file-
systems. At the moment I've created a ramdisk and made an
ext2 partition in it (which is compressed as I appli

I have a piece of code that is trying to use sendmsg() on a raw socket to inject
a UDP packet onto an ethernet link. The destination IP address is set to
another machine on the same subnet, and the packet arrives at its destination.
Thus far all is well.
However, inspection of the ethernet head

If only... block_read() vs. block_write() has the same race. I'm going
through the list of all wait_on_buffer() users right now.

I have not tried it, but I would think that setting HZ to 1024
should make a big improvement in responsiveness.
Currently, the time slice allocated to a standard Linux process
is 5*HZ, or 50ms when HZ is 100. That means that you will notice
keystrokes being echoed slowly in X whe
