mount_msdosfs and longnames

My newest build of FreeBSD 7.0-CURRENT from today (11/18/2005) shows a 
behaviour on MSDOS mounted drives that I never saw before:

As always I mounted my FAT32 partitions like this:

# mount_msdosfs /dev/ad0s5 /WINDAT

In the past I got full access on long formatted names for directories 
and files. With my newest build there are only short names in 8.3 
convention, all in small letters.


The option '-o longnames' (as described in manpage mount_msdosfs) gives 
the following error:

# mount_msdosfs: /dev/ad0s5: Invalid argument

Option '-o longname' (without ending 's') does the mount, but names 
remain in 8.3 convention.


Looking in /usr/src/sys/fs/msdosfs/msdosfs_vfsops.c [Version 1.147 from 
2005/10/31 15:41:20] there is a naming discrepancy against the manpage: 
supported options are 'shortname' and 'longname' without s. I hope I did 
not misunderstood this.


FYI: The mount and access on my NTFS formatted drives seems to function 
normal.

Has anybody else observed this behaviour? Any ideas?


Thanks in advance,
