After I compile the kernel again, this has been fixed. Maybe I've done
something wrong before. Thank you!

As Yanming reported in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=215914
The root cause is: in a very small sized image, it's very easy to
exceed threshold of foreground GC, if we calculate free space and
dirty data based on section granularity, in corner case,
has_not_enough_free_secs
Now that ci_match is part of libfs, make f2fs reuse it instead of having
a different implementation.

This is the v2 of this series. it applies Eric's comments and extend
the series to complete the merge of generic_ci_match for ext4 and f2fs.

The existence of fname->cf_name.name requires s_encoding & IS_CASEFOLDED,
therefore this can be simplified.

ext4_ci_compare originally follows utf8_*_strcmp, which means return
zero on match. This means that every usage of that in ext4 negates
the return.
Turn it into a predicate function, let it follow the kernel convention
and return true on match, which means it's now the same as its f2fs
counterpar
If the volume is in strict mode, ext4_ci_compare can report a broken
encoding name. This will not trigger on a bad lookup, which is caught
earlier, only if the actual disk name is bad.

By using a new type here, we can hide most of the caching casefold logic
from ext4. The condition in ext4_match is now quite redundant, but this
is addressed in the next patch.
This doesn't use ext4_filename to keep it generic, since the function
will be moved to libfs to be shared with f2fs.
Si
Matching case-insensitive names is a generic operation and can be shared
with f2fs. Move it next to the rest of the shared casefold fs code.
