IO is now more prepared to be asynchronous. Some headers have been pulled apart. Signed-off-by: Pedro Falcato <[email protected]>
This makes most text editors (nano, bim) work well on the vterm with TERM=linux. irssi still has some issues. Signed-off-by: Pedro Falcato <[email protected]>
Waking the address while holding the inode spinlock will result in a deadlock, as wait_for callers (on the inode) will sometimes want to hold the inode lock. Signed-off-by: Pedro Falcato <[email protected]>

This commit fixes up a variety of headers for C support on things such as filesystem drivers. It has a couple of hacks, and some stuff just isn't there yet (struct process, for one). Signed-off-by: Pedro Falcato <[email protected]>
The date calculation had lots of problems, and was giving out an extra day. Fix it, and add it to time.cpp instead of having it in PC's rtc driver. Signed-off-by: Pedro Falcato <[email protected]>

Lots of hacks, and most functions will probably not be callable from C (due to missing extern "C"). Signed-off-by: Pedro Falcato <[email protected]>

This lets us generically merge bios into requests, which are essentially a list of bios for the same sector range (and the same OP) which drivers will be able to ingest instead of bios. Queue properties let us merge these and split these according to the underlying hardware. Signed-off-by: Pedro Falcato <[email protected]>

Spinlock was brought over from Carbon, and is old and unused. Signed-off-by: Pedro Falcato <[email protected]>
Add local_lock, a nice abstraction over preemption disabling and irq disabling. Signed-off-by: Pedro Falcato <[email protected]>

If the fs is relatively unfragmented, plugging requests should have a really great effect in reducing the amount of tiny writes we do. Signed-off-by: Pedro Falcato <[email protected]>
