All filesystems that currently support UTF-8 casefold can fetch the UTF-8 version from the filesystem metadata stored on disk. They can get the data stored and directly match it to a integer, so they can skip the string parsing step, which motivated the removal of this function in the first place. However, for tmpfs, the only way to tell the kernel which UTF-8 version we are about to use is via mount options, using a string. Re-introduce utf8_parse_version() to be used by tmpfs. This version differs from the original by skipping the intermediate step of copying the version string to an auxiliary string before calling match_token(). This versions calls match_token() in the argument string. The paramenters are simpler now as well. utf8_parse_version() was created by |
