Kernel: Start work on making tty a file
...
TTY is now a file that you can read from/write to. I still have
to port shell to use this new interface

Kernel: Improve locking in Process, VFS and ATAController
...
We used to block on all process access. This meant that shell
reading the keyboard input would block all VFS access making disk
accesses practically impossible. We now block only when it is
necessary :)

Kernel: Thread is no longer RefCounted
...
This makes developement with Scheduler much easier against compiler
optimizations. I could now remove the pragma GCC optimize stuff.

Everything is now done through a file descriptor.

I realized you cannot return a stirng view and it to be thread safe

Kernel: Create RecursiveSpinLock and add it to Process
...
We now lock every function within Proccess, just to be sure.
Recursive lock allows us to use lock from the same thread even if
we already have the spinlock locked

Kernel: Lock process functions instead of the ata controller
...
Process has to use locks at least on some functions so multithreaded
disk io is safe. This seemed to fix corrupted reads from disk

Kernel: Rework filesystem reading
...
We now read from a filesystem to user provided buffer.
Read sizes are determined by read call.
You should now get file descriptors and do reading through Process::current()
