2019-08-07	ext: vfs.FileDescriptionImpl and vfs.FilesystemImpl implementations.	Ayush Ranjan
	- This also gets rid of pipes for now because pipe does not have vfs2 specific support yet. - Added file path resolution logic. - Fixes testing infrastructure. - Does not include unit tests yet. PiperOrigin-RevId: 262213950
2019-07-30	ext: Migrate from using fileReader custom interface to using io.Reader.	Ayush Ranjan
	It gets rid of holding state of the io.Reader offset (which is anyways held by the vfs.FileDescriptor struct. It is also odd using a io.Reader becuase we using io.ReaderAt to interact with the device. So making a io.ReaderAt wrapper makes more sense. Most importantly, it gets rid of the complexity of extracting the file reader from a regular file implementation and then using it. Now we can just use the regular file implementation as a reader which is more intuitive. PiperOrigin-RevId: 260846927
2019-07-30	ext: block map file reader implementation.	Ayush Ranjan
	Also adds stress tests for block map reader and intensifies extent reader tests. PiperOrigin-RevId: 260838177
2019-07-29	Migrate from using io.ReadSeeker to io.ReaderAt.	Ayush Ranjan
	This provides the following benefits: - We can now use pkg/fd package which does not take ownership of the file descriptor. So it does not close the fd when garbage collected. This reduces scope of errors from unexpected garbage collection of io.File. - It enforces the offset parameter in every read call. It does not affect the fd offset nor is it affected by it. Hence reducing scope of error of using stale offsets when reading. - We do not need to serialize the usage of any global file descriptor anymore. So this drops the mutual exclusion req hence reducing complexity and congestion. PiperOrigin-RevId: 260635174

	PiperOrigin-RevId: 258645957
2019-07-11	Added tiny ext4 image.	Ayush Ranjan
	The image is of size 64Kb which supports 64 1k blocks and 16 inodes. This is the smallest size mkfs.ext4 works with. Added README.md documenting how this was created and included all files on the device under assets. PiperOrigin-RevId: 257712672
2019-07-11	ext: boilerplate code.	Ayush Ranjan
	Renamed ext4 to ext since we are targeting ext(2/3/4). Removed fs.go since we are targeting VFS2. Added ext.go with filesystem struct. PiperOrigin-RevId: 257689775
