Message:

o File resize optimization: The JFS, HPFS and probably NET

will never return space which isn't zeroed when expanding
a file. Associate a file system information object with the
filehandles to keep track of such features. This also fixes
the fsStatFH() implementation trouble.
This attribute doesn't apply to CDFS. While RAMFS fails
the test, it zeros at open but not at setfilesize.

o Fixed invalid inode and dev numbers for new files, was passing

the wrong path around.
