Updated UID handling

[mike-matera]

Hi Javier,

I've created a pull request that fixes some compile issues with the scull driver. I may fix others if I have time before class!

Cheers

current_uid().val
current_euid().val
to all instances!

[bodgergely]

it compiles cleanly after that

Hi bodgergely.. That does work but I don't think it's the right thing to do. I used the functions defined in the kernel (uid_eq() and such) to compare uids. Using those guards against future changes to the kuid structures.

The changes are shown in my pull request.

[bodgergely]

Yeah, you are right about not relying on the internals directly. Thanks I will use that function instead.

I'm closing this because it was already fixed by commit 0a7ee7d ("Fix failure to compile the scull.").
