Subject: [PATCH 0/3] Make UTF-8 encoding loadable

utf8data.h_shipped has a large database table which is an auto-generated
decodification trie for the unicode normalization functions and it is not
necessary to carry this large table in the kernel.
Goal is to make UTF-8 encoding loadable by converting it into a module
and adding a layer between the filesystems and the utf8 module which will
load the module whenever any filesystem that needs unicode is mounted.
Unicode is the subsystem and utf8 is a charachter encoding for the
subsystem, hence first two patches in the series are renaming functions
and file name to unicode for better understanding the difference between
UTF-8 module and unicode layer.
Last patch in the series adds the layer and utf8 module.

Shreeya Patel (3):
  fs: unicode: Rename function names from utf8 to unicode
  fs: unicode: Rename utf8-core file to unicode-core
  fs: unicode: Add utf8 module and a unicode layer
