ba0a2a3e2f AK: Hide the infallible make<T> factory function from the Kernel 
This function has no users, nor should it ever be used in the kernel,
as all allocation failures in the Kernel should be explicitly checked.

7933a9b6c8 AK: Stop using the make<T> factory function in Trie 
This function is infallible, and so we would like to exclude it from
the Kernel, which includes this header.

3dc8bbbc8b Kernel: Remove the infallible make_ref_counted<T> factory function 
This function had no users, nor should it ever be used, as all
allocation failures in the Kernel should be explicitly checked.

a65bbbdb71 Kernel: Convert try_make_ref_counted to use ErrorOr 
This allows more ergonomic memory allocation failure related error
checking using the TRY macro.

8289727fac Kernel: Stop using the make<T> factory method in the Kernel 
As make<T> is infallible, it really should not be used anywhere in the
Kernel. Instead replace with fallible `new (nothrow)` calls, that will
eventually be error-propagated.

e5e7cb822a Kernel: Ignore allocation failures when trying to retransmit packets 
We ignore allocation failures above the first 16 guaranteed socket
slots, as we will just retransmit their packets the next time around.

2dc91865a4 Kernel: Stop allocating VirtIO configuration structs on the heap 
These are trivially-copyable 12-byte structs, so there's no point in
allocating them on the heap.

be4c144524 AK: Support formatting Vectors with any inline_capacity 
The default Vector type has its inline capacity set to 0, which means
any Vector with non-zero inline capacity was unformattable.

a4cb6a49ae FileManager: Disable "View as..." actions for desktop DirectoryView 
This stops these actions from being activated with Ctrl+[1,2,3] or the
command palette.. Switching to table or columns view would just hide
all the icons, so let's not make those options available.

34f6c88ffd Revert "Kernel: Protect InodeWatcher internals with spinlock instead of mutex" 
This reverts commit 0bebf013e3.

This caused a deadlock when handling a crashed process, so let's revert
it until we can figure out what went wrong.

248832f438 Kernel: Convert OpenFileDescriptor from mutex to spinlock 
A mutex is useful when we need to be able to block the current thread
until it's available. This is overkill for OpenFileDescriptor.

First off, this patch wraps the main state member variables inside a
SpinlockProtected<State> to enforce synchronized access. This also
avoids "free locking" where figuring out which variables are guarded
by which lock is left as an unamusing exercise for the reader.

Then we remove mutex locking from the functions that simply call through
to the underlying File or Inode, since those fields never change anyway,
and the target objects perform their own synchronization.

the other buttons in this window.

2b14a11238 LibC: Add IN6_IS_ADDR_LINKLOCAL to in.h 
I tried the OpenSSH port but it failed to compile due to a missing
definition of this macro. It's simple enough to add, and it's addition
allowed OpenSSH to compile once again.

I also went ahead and added spec comments for these macros as well.

e8857f9b2d CrashReporter: Stop attempting to lockdown the process veil 
The idea of locking the process veil in CrashReproter is well
intentioned, but ultimately frought with issues.

The fundamental premise is a bit flawed, as we are using the crashing
program as input to dynamically add new paths to the process veil.
This means that an attacker can potentially produce a custom or
malformed binary to trick CrashReporter into allowing an arbitrary
path to be read.

Also, finally added a Formatter for StyleValues.
