Shell also has better line wrapping. You still can't visually go
back to previous line, but atleas we now write from the beginning

Kernel: Ext2 directory functions now fail on invalid blocks
...
Invalid blocks should only happen while writing to a file and
I think in that case we should just bail out instead of giving
you incomlete inode list or search result.

I had misread the format and the parsing code was incorrect. I also

Kernel: Create CriticalScope and fix kmalloc
...
This disables interrupts for the current scope and restores them
after the scope. This is used in kmalloc, since scheduler might
call into kmalloc/kfree, but deadlock if some thread is currently
trying to allocate. This allows us to use kmalloc in Scheduler.
