2020-09-09	Clarify seek behaviour for kernfs.GenericDirectoryFD.	Rahat Mahmood
	- Remove comment about GenericDirectoryFD not being compatible with dynamic directories. It is currently being used to implement dynamic directories. - Try to handle SEEK_END better than setting the offset to infinity. SEEK_END is poorly defined for dynamic directories anyways, so at least try make it work correctly for the static entries. Updates #1193. PiperOrigin-RevId: 327890128
2020-09-09	Consistent precondition formatting	Michael Pratt
	Our "Preconditions:" blocks are very useful to determine the input invariants, but they are bit inconsistent throughout the codebase, which makes them harder to read (particularly cases with 5+ conditions in a single paragraph). I've reformatted all of the cases to fit in simple rules: 1. Cases with a single condition are placed on a single line. 2. Cases with multiple conditions are placed in a bulleted list. This format has been added to the style guide. I've also mentioned "Postconditions:", though those are much less frequently used, and all uses already match this style. PiperOrigin-RevId: 327687465
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
2020-07-23	FileDescription is hard to spell.	Dean Deng
	Fix typos. PiperOrigin-RevId: 322913282
2020-07-14	Include context in kernfs.Inode.Stat method	Craig Chi
	To implement stat(2) in FUSE, we have to embed credentials and pid in request header. The information should be extracted from the context passed to VFS layer. Therefore `Stat()` signature in `kernfs.Inode` interface should include context as first argument. Some other fs implementations need to be modified as well, such as devpts, host, pipefs, and proc. Fixes #3235
2020-06-17	Implement POSIX locks	Fabricio Voznika
	- Change FileDescriptionImpl Lock/UnlockPOSIX signature to take {start,length,whence}, so the correct offset can be calculated in the implementations. - Create PosixLocker interface to make it possible to share the same locking code from different implementations. Closes #1480 PiperOrigin-RevId: 316910286
2020-06-09	Implement flock(2) in VFS2	Fabricio Voznika
	LockFD is the generic implementation that can be embedded in FileDescriptionImpl implementations. Unique lock ID is maintained in vfs.FileDescription and is created on demand. Updates #1480 PiperOrigin-RevId: 315604825
2020-05-18	Remove IfChange/ThenChange lint from VFS2	Fabricio Voznika
	As new functionality is added to VFS2, corresponding files in VFS1 don't need to be changed. PiperOrigin-RevId: 312153799
2020-05-07	Allocate device numbers for VFS2 filesystems.	Jamie Liu
	Updates #1197, #1198, #1672 PiperOrigin-RevId: 310432006
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
2020-04-24	Plumb context.Context into kernfs.Inode.Open().	Dean Deng
	PiperOrigin-RevId: 308304793
2020-04-24	Fixes for procfs	Fabricio Voznika
	- Return ENOENT for /proc/[pid]/task if task is zoombied or terminated - Allow directory to be Seek() to the end - Construct synthetic files for /proc/[pid]/ns/* - Changed GenericDirectoryFD.Init to not register with FileDescription, otherwise other implementation cannot change behavior. Updates #1195,1193 PiperOrigin-RevId: 308294649
2020-04-23	Port devpts to VFS2.	Nicolas Lacasse
