We pass a NULL destination address, so we need to keep the added
NULL check, but after the previous commit we can now use the
real hook function here.
WiFi still works (tested with realtekwifi.)
This is what FreeBSD does. The default implementation (in this
same file) does what ether_output did before, but the FreeBSD
net80211 stack overrides the method.
IORequest notifications begin by notifying the "finished" condition,
then invoking the request callback, then invoking the parent callback.
vfs_{read|write}_pages wait on the "finished" condition and then
return at once, potentially releasing their references to the vnode
in question, before the request callback is even invoked. The request
callback is what (eventually) invokes iterative_io_finished_hook,
which meant that we were accessing the Inode object after our reference
to it had already been released.
We can't really change IORequest notification order, as any one of the
notifications could delete the request, and indeed the first one does here.
So the solution is just to acquire another reference to the vnode and
release it in the finished hook.
Fixes #19122 and #8405.
* Use do_fd_io and drop the unnecessary iteration callback.
* Make the callback call a non-static function to avoid needing
to fetch values.
* Unlock the cache before calling the I/O function.
Should fix #19259.
If get_vecs returns 0 and no vecs, then we need to quit iterating.
Otherwise we'll just loop forever and leak memory.
Also add an assert in IOBuffer::GetNextVirtualVec that would have caught
this problem, and the memory leak it results in.
We need to hold a reference to the file descriptor throughout
the I/O operation, which do_iterative_fd_io already takes care of.
So just modify it to handle not having the additional callbacks.
Nothing actually uses do_fd_io at present, though it will be
in the next commits.
* Spirograph uses SetBits with length 1 und 4, which can't work as
expected. As Spirograph uses the same source and target colorspace,
the memcpy codepath is used with the right length.
* fix #12931

Previously it was not initialized until "post-VM", but there are
a number of ways VM initialization can go wrong that it would
be nice to know about without needing a serial port.
On arches which map the whole physical memory into the kernel
address space (x86_64, at least), we can get the bluescreen facility
initialized using KERNEL_PMAP_BASE. On other architectures, we
just fail to init then, and do the usual setup later on.
A slight bit of extra code cleanup in blue_screen_init_early:
we now just call module->info.std_ops() rather than a
frame-buffer-console specific method.
If the vnode's reference count is already > 0 and we can increment
it from there, then we know it's already used and we don't need
to run any further checks. This saves us having to acquire the
vnode lock every single time we want to get the vnode.
(IsBusy() doesn't use an atomic get to fetch the flags value,
but as this is the first read of the value after having acquired
the vnode lock, that should not be a problem.)
Adjust free_vnode, while at it, to not set a positive reference count
during destruction, to be fully certain nothing will see this vnode
as being available for use, and add an assertion checking this.
Improves "git status" time significantly, at least in the case where
all vnodes are in the disk caches. This fast path also seems to be hit
very many times (> 100,000) on boot, and in compile jobs, too.

This lock protects a linked-list. In all cases but one, the only
operation done while holding the lock is to remove a single item
from the list and decrement a counter. Acquiring a mutex itself
involves multiple linked-list operations protected by spinlocks,
so cut out the overhead and just use a spinlock directly.
In the one case where we do more than just remove an item, we
hold an additional write-lock, and so we don't run any risk of
causing "spinlock could not be acquired for a long time" KDLs,
as in that case the threads will be waiting on the rwlock instead.
Reduces lock contention in the VFS. Compiling HaikuDepot and the
mime_db with -j4 (in a VM), the sys time decreased a bit (~10.1s
to ~9.9s), and real time went down by more (~31s to ~29s.) "git status"
performance also improved a bit, but we seem to be contending for
vnode locks now in that case.
Avoids needing a nonstandard "offsetof", and inlines more methods.
No behavioral change intended.
Also rename "next" to "hash_next" for clarity, and remove an unused
"next" field from LockWaiter.
Applications that don't call open() or like functions too often,
and call many FD-related methods across multiple threads at once
(like "git status") now don't wait on the context lock as much.
("git status" performance isn't much improved because threads just
hit the "unused vnodes" lock instead.)
