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.
