to set ownership and mode in the same setattr operation, the mode was
overwritten by secpolicy_vnode_setattr().

PR:	kern/118320
Submitted by:	Mark Thompson <info-gentoo@mark.thompson.bz>

r197842:

Fix white-spaces.

r197843:

On FreeBSD it is enough to report provider removal when orphan event is
received, we don't have to do it on every ENXIO error in I/O path.
Solaris has no GEOM so they have to handle it in a less clean way.

r197860:

File system owner is when uid matches and jail matches.

r197861:

Allow file system owner to modify system flags if securelevel permits.
