Hi Folks,
I have to "maintain" an existing kernel module code.
It was written for 2.4 and has a open, read and write calls from
inside kernel module.
sample code being this:
// memory management segment access
fs = get_fs();
set_fs(KERNEL_DS);
// open the file with the firmware for PIC for uploading
if (ifp = open( filename, O_RDONLY, 0 ), ifp < 0)
{
Now, when I am trying to compile same code for 2.6, I am getting
compilation warning and load time error saying
Undefined Symbol: open, read not found ..
I know that ideally one isn't supposed to file operations from inside
kernel modules.
But, this time case is diff. and I have to try to maintain code legacy
(please dont ask me why)
So, without getting into that debate could someone please help me
understand what am I missing.
Can I use open, read call like 2.4 here or not ??
If not, why ??
What other options do I have ?
TIA,
Alfred
