2021-09-17	Move CtxIPCNamespace to kernel/ipc package.	Zyad A. Ali
	CtxIPCNamespace is needed by mqfs package to be able to retreive an IPCNamespace using ctx.Value. As ctx.Value compares keys as interfaces, we need to use type kernel.contextID in package mqfs, which is not possible due to circular depenedency, so move it to kernel/ipc instead. Updates #136
2020-11-13	Check for misuse of kernel.Task as context.Context.	Jamie Liu
	Checks in Task.block() and Task.Value() are conditional on race detection being enabled, since these functions are relatively hot. Checks in Task.SleepStart() and Task.UninterruptibleSleepStart() are enabled unconditionally, since these functions are not thought to lie on any critical paths, and misuse of these functions is required for b/168241471 to manifest.

2020-10-14	Fix shm reference leak.	Dean Deng
	All shm segments in an IPC namespace should be released once that namespace is destroyed. Add reference counting to IPCNamespace so that once the last task with a reference on it exits, we can trigger a destructor that will clean up all shm segments that have not been explicitly freed by the application.

2020-06-16	Port aio to VFS2.	Nicolas Lacasse
	In order to make sure all aio goroutines have stopped during S/R, a new WaitGroup was added to TaskSet, analagous to runningGoroutines. This WaitGroup is incremented with each aio goroutine, and waited on during kernel.Pause. The old VFS1 aio code was changed to use this new WaitGroup, rather than fs.Async. The only uses of fs.Async are now inode and mount Release operations, which do not call fs.Async recursively. This fixes a lock-ordering violation that can cause deadlocks. Updates #1035.

2020-01-27	Update package locations.	Adin Scannell
	Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
