4 ZoneFS - Zone filesystem for Zoned block devices
11 as a file. Unlike a regular POSIX-compliant file system with native zoned block
17 As such, zonefs is in essence closer to a raw block device access interface
18 than to a full-featured POSIX file system. The goal of zonefs is to simplify
21 direct block device file ioctls which may be more obscure to developers. One
22 example of this approach is the implementation of LSM (log-structured merge)
