Subject: [PATCH v2 00/15] NLS refactor and UTF-8 normalization
* Archive of previous versions:
https://www.spinics.net/lists/linux-fsdevel/msg125523.html
The goal of this patchset is to adapt the NLS subsystem to support
full UTF-8 normalization and casefold operations for specific versions
of unicode. There are many use cases of this feature and, while my
specific interest is on case-insensitiveness for local filesystems, I am
aware this might be in the wishlist of people working on SMB, NFS and
others.
The first part of the patchset refactors the NLS subsytem to allow
multiple tables of the same encoding (differentiated by the version) in
an inexpensive way. It also create hooks for some higher-level
operations, like comparisons and normalization. A new interface is
exported to request a specific version of the charset.
The second part of the patchset introduces the utf8 normalization code
as a new NLS charset. It is implemented as a separated charset, called
utf8n to preserve curent behavior of the nls_utf8 charset. The
normalization core is provided by the SGI patches from 2014, which I
refactored, adapted and updated to unicode 10.0.0.
The last patch is a test module, which does some sanity check on the
normalization code when it is loaded.
As usual, the unicode source files are not part of the patch because
they are too big and would bounce the emails. Which means that kbuild
will complain about not being able to generate ucd/*.txt files.
Kbuild will also complain about code that is just being moved, which I'm
not going to fix at this time. please refer to v1, for more information.
