2020-09-17	fsimpl: improve the "implements" comments	Tiwei Bie
	As noticed by @ayushr2, the "implements" comments are not consistent, e.g. // IterDirents implements kernfs.inodeDynamicLookup. // Generate implements vfs.DynamicBytesSource.Generate. This patch improves this by making the comments like this consistently include the package name (when the interface and struct are not in the same package) and method name.

2020-08-28	Implement StatFS for various VFS2 filesystems.	Rahat Mahmood
	This mainly involved enabling kernfs' client filesystems to provide a StatFS implementation. Fixes #3411, #3515. PiperOrigin-RevId: 329009864
2020-08-03	Plumbing context.Context to DecRef() and Release().	Nayana Bidari
	context is passed to DecRef() and Release() which is needed for SO_LINGER implementation. PiperOrigin-RevId: 324672584
2020-05-07	Allocate device numbers for VFS2 filesystems.	Jamie Liu
	Updates #1197, #1198, #1672 PiperOrigin-RevId: 310432006
2020-05-05	Update vfs2 socket TODOs.	Dean Deng
	Three updates: - Mark all vfs2 socket syscalls as supported. - Use the same dev number and ino number generator for all types of sockets, unlike in VFS1. - Do not use host fd for hostinet metadata. Fixes #1476, #1478, #1484, 1485, #2017. PiperOrigin-RevId: 309994579
2020-05-05	Return correct name for imported host files	Fabricio Voznika
	Implement PrependPath() in host.filesystem to correctly format name for host files. Updates #1672 PiperOrigin-RevId: 309959135
2020-05-01	Port netstack, hostinet, and netlink sockets to VFS2.	Dean Deng
	All three follow the same pattern: 1. Refactor VFS1 sockets into socketOpsCommon, so that most of the methods can be shared with VFS2. 2. Create a FileDescriptionImpl with the corresponding socket operations, rewriting the few that cannot be shared with VFS1. 3. Set up a VFS2 socket provider that creates a socket by setting up a dentry in the global Kernel.socketMount and connecting it with a new FileDescription. This mostly completes the work for porting sockets to VFS2, and many syscall tests can be enabled as a result. There are several networking-related syscall tests that are still not passing: 1. net gofer tests 2. socketpair gofer tests 2. sendfile tests (splice is not implemented in VFS2 yet) Updates #1478, #1484, #1485 PiperOrigin-RevId: 309457331
2020-04-27	Import host sockets.	Dean Deng
	The FileDescription implementation for hostfs sockets uses the standard Unix socket implementation (unix.SocketVFS2), but is also tied to a hostfs dentry. Updates #1672, #1476 PiperOrigin-RevId: 308716426
2020-04-24	Plumb context.Context into kernfs.Inode.Open().	Dean Deng
	PiperOrigin-RevId: 308304793
2020-04-24	Move hostfs mount to Kernel struct.	Dean Deng
	This is needed to set up host fds passed through a Unix socket. Note that the host package depends on kernel, so we cannot set up the hostfs mount directly in Kernel.Init as we do for sockfs and pipefs. Also, adjust sockfs to make its setup look more like hostfs's and pipefs's. PiperOrigin-RevId: 308274053
2020-04-03	Add FileDescriptionImpl for Unix sockets.	Dean Deng
	This change involves several steps: - Refactor the VFS1 unix socket implementation to share methods between VFS1 and VFS2 where possible. Re-implement the rest. - Override the default PRead, Read, PWrite, Write, Ioctl, Release methods in FileDescriptionDefaultImpl. - Add functions to create and initialize a new Dentry/Inode and FileDescription for a Unix socket file. Updates #1476 PiperOrigin-RevId: 304689796
2020-03-31	Add socket filesystem and global disconnected socket mount for VFS2.	Dean Deng
	A socket mount where anonymous sockets will reside is added to the VirtualFilesystem. Socketfs is built on top of kernfs. Updates #1476, #1478, #1484, #1485. PiperOrigin-RevId: 304095251
