Pull zonefs updates from Damien Le Moal:

 - Reorganize zonefs code to split file related operations to a new
   fs/zonefs/file.c file (me)

 - Modify zonefs to use dynamically allocated inodes and dentries (using
   the inode and dentry caches) instead of statically allocating
   everything on mount. This saves a significant amount of memory for
   very large zoned block devices with 10s of thousands of zones (me)

 - Make zonefs_sb_ktype a const struct kobj_type (Thomas)
