Subject: buffer cache
Date: Sat, 28 Apr 2001 23:51:43 -0700
Does all disk I/O go through buffer cache? All superblcok, inodes and
data block access must go thourgh buffer cache and can not pass it? So if OS
want to write some data to disk, it must copy to the corrsponding blocks in
buffer cache and mark it dirty, then at certain time, flush to disk?
Is there any possibility disk I/O passby buffer cache?
Thanks in advance.

I am working something in Linux Kernel. I just
want to write to a file when I was in kernel.
What should I do?
Thanks in advance!

Subject: More on reading ethernet frames
Date: Sun, 29 Apr 2001 19:13:13 +1200
Hello, I've happily got my program reading raw ethernet
frames, using a socket( AF_PACKET, SOCK_RAW, ETH_P_ALL),
but when decoding, I occasionally get bad packets, or
possibly even network protocols that are unsupported.
This is bad, since it means that I don't know where the
next ethernet frame starts, and therefore have to abondon
decoding the data.
Does anyone know of either some real documentation for
this, other than the man page for packet?
Or does anyone know how I can distinguish the end of
a frame from the socket, or how to read a whole frame
at a time?
Thanks in advance.

Date: Sun, 29 Apr 2001 11:27:50 +0200
Hi everybody,
trying to compile a program written en C, I receive this message and I
don't know what the hell I can do, please, HELP!
Don't worry, is like this because of I put the linker verbose to try to
find something wrong ;)
If someone want I can send him the source code and he can try to compile
it by himself, it's around 800 Kb.
Thank you very much.
