Subject: accessing file operations directly in the kernel
Date: Thu, 6 Nov 2008 22:39:59 +0000	[thread overview]
Message-ID: <2c918050811061439k450bf4baqd02c054022249b35@mail.gmail.com> (raw)

Hi,

I am dealing with an interesting situation, which I have to access a
serial device driver
from the kernel space. I tried to use sys_open, sys_ioctl ... but
there is a problem
with the file descriptors.  Now, I started using direct calls to the
drivers functions
driver_open, driver_ioctl... passing the *inode from user_path_walk(),
but it doesn't
seem that works right. This serial device is going to be used only
from the other
module that runs in the kernel.

TIA
Andy
