SVN rev 191564 on 2009-04-27 16:46:16Z by rmacklem
Change the semantics of i_modrev/va_filerev to what is required for
the nfsv4 Change attribute. There are 2 changes:
1 - The value now changes on metadata changes as well as data
modifications (incremented for IN_CHANGE instead of IN_UPDATE).
2 - It is now saved in spare space in the on-disk i-node so that it
survives a crash.
Since va_filerev is not passed out into user space, the only current
use of va_filerev is in the nfs server, which uses it as the directory
cookie verifier. Since this verifier is only passed back to the server
by a client verbatim and then the server doesn't check it, changing the
semantics should not break anything currently in FreeBSD.
