It turned out that most of the removed code was dead anyway and it took
just a few lines of code to restore support for case-insensitive
filesystems. Filesystems with mixed case sensitivity behave exactly the
same as case-sensitive filesystem as it has always been the case on FreeBSD.
Anyway the big change has just been committed:
Please test away.
Another note is that the filesystem name cache is now disabled for case
insensitive filesystems and filesystems with normalization other than
none. That may hurt the lookup performance, but should ensure
correctness of operations.
