Here is how it goes - I have written a small test driver as an exercise to "Linux Device Drivers" and as a preparation for writing a real, functional driver.
For the sake of seeing how far I got it working (I already implemented the open(0, read(), write() and ioctl() calls) I wrote a simple programm which queries some information from the driver:
When I try to compile it however, I get the following errors:
Here is the struct in which the problem occurs:
So, this two structures of the char dev and the semaphore are defined without "typedef"-s or anithing else in the kernel source. Anyone ahs a clue how to get rid of this errors?
As far as the compilation of the driver itself, everithing goes well.
Here's a link to the actual driver source code, which I wrote.
Dear colleagues,

"array type has incomplete element type". Any body can provide a solution for it.

Hi Gurues,
I need to modify an existing script that uses find to search a folder, and then move its contents to a folder. What I need to do is run gzip on each file after it's moved.
So, I ran this little test:
Put a ls.tar file on my $HOME, mkdir tmp, and then:
