Subject: [GIT PULL for v6.11] vfs casefold

Hey Linus,

/* Summary */
This contains some work to simplify the handling of casefolded names:

- Simplify the handling of casefolded names in f2fs and ext4 by keeping the
  names as a qstr to avoiding unnecessary conversions.

- Introduce a new generic_ci_match() libfs case-insensitive lookup helper and
  use it in both f2fs and ext4 allowing to remove the filesystem specific
  implementations.

- Remove a bunch of ifdefs by making the unicode built checks part of the code
  flow.

/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)

All patches are based on v6.10-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */
No known conflicts.
