2021-06-03	Kernel: Switch ProcessGroup to IntrusiveList from InlineLinkedList	Brian Gianforcaro

2021-05-21	Revert "Kernel: Avoid allocating under spinlock in ProcessGroup::find_or_create"	Brian Gianforcaro
	This reverts commit e95eb7a51d8295c96cddf20f116139deecbb69d4. This is causing some sort of list corruption, as evident by #7313 I haven't been able to figure it out yet, so lets revert this change until I can figure out what's going on.
2021-05-20	Kernel: Avoid allocating under spinlock in ProcessGroup::find_or_create	Brian Gianforcaro
	Avoid allocating while holding the g_process_groups_lock spinlock, it's a pattern that has a negative effect on performance and scalability, especially given that it is a global lock, reachable by all processes.
2021-05-20	Kernel: Make ProcessGroup::find_or_create API OOM safe	Brian Gianforcaro
	Make ProcessGroup::find_or_create & ProcessGroup::create OOM safe, by moving to adopt_ref_if_nonnull.
2021-04-22	Everything: Move to SPDX license identifiers in all files.	Brian Gianforcaro
	SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
2020-11-30	Kernel: Move block condition evaluation out of the Scheduler	Tom
	This makes the Scheduler a lot leaner by not having to evaluate block conditions every time it is invoked. Instead evaluate them as the states change, and unblock threads at that point. This also implements some more waitid/waitpid/wait features and behavior. For example, WUNTRACED and WNOWAIT are now supported. And wait will now not return EINTR when SIGCHLD is delivered at the same time.
2020-08-19	Kernel: Distinguish between new and old process groups with equal pgids	AnotherTest
	This does not add any behaviour change to the processes, but it ties a TTY to an active process group via TIOCSPGRP, and returns the TTY to the kernel when all processes in the process group die. Also makes the TTY keep a link to the original controlling process' parent (for SIGCHLD) instead of the process itself.
