Subject: [PATCH RESEND v2 05/25] nls: Split struct nls_charset from struct nls_table
In order to support multiple versions of the same encoding, we want to
split the charset registering data, which enrolls it with the NLS
subsystem and is valid for all versions of the encoding, from the
version specific data, that is actually going to be returned when the
caller loads an NLS charset.
With the exception of the following files (files declaration and default
charset), which were edited by hand, the other files were generated with
the following Coccinelle patch:
Files edited by hand:
- fs/nls/nls_base.c
