The previous format skipped many important structs that are pointers, especially for cgroups. Change to print as json, removing parts of the spec that are not relevant. Also removed debug message from gofer that can be very noisy when directories are large. PiperOrigin-RevId: 316713267

2020-06-16Port 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.

2020-06-15TCP to honor updated window size during handshake.Mithun Iyer
In passive open cases, we transition to Established state after initializing endpoint's sender and receiver. With this we lose out on any updates coming from the ACK that completes the handshake. This change ensures that we uniformly transition to Established in all cases and does minor cleanups. Fixes #2938 PiperOrigin-RevId: 316567014
