Subject: [PATCH v4 00/23] Ext4 Encoding and Case-insensitive support
Hi,
[Resending to include fsdevel, as requested by Dave Chinner]
Following the e2fsprogs changes, these are the corresponding kernel-side
modifications to support the fname_encoding feature.
The patches are split in two parts. The fist 14 patches are refactoring
and improvements to the NLS code, including the utf8 normalization
support. The final patches implement the fname_encoding feature in ext4.
To test this feature, you need to use the tip of e2fsprogs branch, which
already include support for enabling this feature.
As usual, the ucd files are not included in this email because they are
too large, and would actually cause the email message to bounce.
There are two test files for this in a private xfstests branch, that I
plan to submit upstream once we get this series merged:
https://gitlab.collabora.com/krisman/xfstests.git -b encoding_v4
I also tested this with the xfstests smoke tests using two scenarios:
(1) a non-encoding TEST_DEV; (2) a utf8 enabled TEST_DEV. On both
cases, no unrelated regressions where observed. With my branch of
xfstests above, that fixes some related tests, I didn't observe any
regressions.
