  • d6f41217a   FROMLIST: unicode: Add utf8_casefold_hash ... Browse Code »

    This adds a case insensitive hash function to allow taking the hash
    without needing to allocate a casefolded copy of the string.

    Test: Boots, /data/media is case insensitive

  • 3ae72562a   ext4: optimize case-insensitive lookups ... Browse Code »

    Temporarily cache a casefolded version of the file name under lookup in
    ext4_filename, to avoid repeatedly casefolding it. I got up to 30%
    speedup on lookups of large directories (>100k entries), depending on
    the length of the string under lookup.

  • 9d53690f0   unicode: implement higher level API for string handling ... Browse Code »

    This patch integrates the utf8n patches with some higher level API to
    perform UTF-8 string comparison, normalization and casefolding
    operations. Implemented is a variation of NFD, and casefold is
    performed by doing full casefold on top of NFD. These algorithms are
    based on the core implemented by Olaf Weber from SGI.
