    [XFS] XFS: ASCII case-insensitive support · 189f4bf2
    Barry Naujok authored
    Implement ASCII case-insensitive support. It's primary purpose is for
    supporting existing filesystems that already use this case-insensitive
    mode migrated from IRIX. But, if you only need ASCII-only case-insensitive
    support (ie. English only) and will never use another language, then this
    mode is perfectly adequate.
    ASCII-CI is implemented by generating hashes based on lower-case letters
    and doing lower-case compares. It implements a new xfs_nameops vector for
    doing the hashes and comparisons for all filename operations.
    To create a filesystem with this CI mode, use: # mkfs.xfs -n version=ci
