NOTES.txt

Networking:
Adding bridged connection (only on cabl, not wifi)
# ip link add name br0 type bridge
# ip link set dev br0 up
# ip link set dev eth0(phys int) master br0

TODO:
current_thread ptr at bottom of kernel stack?
RB-tree ordered by runtime to run the one with the lowest runtime
Multi-core
Higher VGA res
brk & sbrk syscalls
Kernel memory cache (SLAB)
Proper locking on kernel structures
Error checking (ERRNO, correct return values)
VFS & Mountpoints
Reference counters and memory freeing (Generic kobjects embedded in data?)
Correct access to and from userspace
Disk driver
Filesystem driver
Runtime and tick-count normalization
2 phase thread killing (stop -> resched -> async kill)
Extended signals w/ usermode handlers
Add delete safe lists
Use regular numbers for signals in usermode
Implement GFP_ATOMIC for memo alloc that cannot sleep
Disable interrupt when handling runqueues in process context
Free unused caches
