Thanks for your reply.
I am interested in where can find the linux kernel spec. file, and where Red
Hat add the smp string?
Where the uname command extract the kernel version information(eg:
2.4.2-2smp or 2.2.16)?
I means from which file, or use which system call?
I am a linux driver writer, and
I see this as the kind of function that should be implemented within the
semaphore interface itself. Very simple - Just wake me up when either 1) I
get the semaphore, or 2) I timed out.
A single implementation saves everyone from attempting to implement this
over and over and over.

2.4.3, non GPF_ATOMIC and non-recursive allocat
Afternoon All-
Basically, I am sending out a pseudo 'help' and bug check. I found
this thread ([BUG] threaded processes get stuck in
rt_sigsuspend/fillonedir/exit_notify) from 9/11/2000. I helping write some
software, and I think I have ran into a bug similiar to this, first, a quick

Hi Guys,
2.4.3 (UP kernel UP machine, http://home.sch.bme.hu/~cell/.config)
oopses when I start lots of pppd eth0 simultaneously.
(I guess the problem is not pppoe specific, but I do not know exactly)
The last pppd sighs: PPP: couldn't register device (-17)
This is 2 oops not just 1...

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

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.

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

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 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

Hi,
The following patch add more disk devices to the SysRq sync list (in both:
-pre and -ac trees). Were the extra IDE devices intentionally omitted here?
BTW, it would be probably nice to add some mon-x86 disk devices here...
