Change 173596 by rwatson at rwatson_cinnamon on 2010/01/23 22:25:15

	Don't allow VOP_SETATTR() on fdescfs -- we could build up a capability
	rights mask for the operations it represents, but it actually isn't very
	coherent conceptually.  For example, you can chmod /dev/fd/X if that fd
	refers to a file, but if you stat() you don't see the file's mode.
