Flushing inodes synchronously

[Constantine Sapuntzakis <csapuntz_(_at_)_zwolle_(_dot_)_lcs_(_dot_)_mit_(_dot_)_edu>]

When v-nodes are kicked out of the vnode cache, their associated
inodes are flushed synchronously to disk (see vinvalbuf in
vfs_subr.c). This seems unnecessary, since the inode buffers already
effectively "delayed" by hanging around in the cache. Am I missing
something here?
