Subject: [PATCH v5 0/4] dedupe smb unicode files
Date: Thu, 17 Aug 2023 01:22:28 +0100 [thread overview]
Message-ID: <20230817002232.80079-1-linux@treblig.org> (raw)
From: "Dr. David Alan Gilbert" <dave@treblig.org>
The smb client and server code have (mostly) duplicated code
for unicode manipulation, in particular upper case handling.
Flatten this lot into shared code.
There's some code that's slightly different between the two, and
I've not attempted to share that - this should be strictly a no
behaviour change set.
In addition, the same tables and code are shared in jfs, however
there's very little testing available for the unicode in there,
so just share the raw data tables.
I suspect there's more UCS-2 code that can be shared, in the NLS code
and in the UCS-2 code used by the EFI interfaces.
Lightly tested with a module and a monolithic build, and just mounting
itself.
