Linus Torvalds 380a129eb2 fs: New zonefs file system 
Zonefs is a very simple file system exposing each zone of a zoned block
 device as a file.
 
 Unlike a regular file system with native zoned block device support
 (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
 sequential write constraint of zoned block devices to the user. As a
 result, zonefs is not a POSIX compliant file system. Its goal is to
 simplify the implementation of zoned block devices support in
 applications by replacing raw block device file accesses with a richer
 file based API, avoiding relying on direct block device file ioctls
 which may be more obscure to developers.
 
 One example of this approach is the implementation of LSM
 (log-structured merge) tree structures (such as used in RocksDB and
 LevelDB) on zoned block devices by allowing SSTables to be stored in a
 zone file similarly to a regular file system rather than as a range of
 sectors of a zoned device. The introduction of the higher level
 construct "one file is one zone" can help reducing the amount of changes
 needed in the application while at the same time allowing the use of
 zoned block devices with various programming languages other than C.
 
 Zonefs IO management implementation uses the new iomap generic code.
 Zonefs has been successfully tested using a functional test suite
 (available with zonefs userland format tool on github) and a prototype
 implementation of LevelDB on top of zonefs.
