Gabriel Krisman Bertazi 3ae72562ad ext4: optimize case-insensitive lookups ... 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.
