New Revision: 197575
URL: http://svn.freebsd.org/changeset/base/197575
Log:
Use correct sizeof() object for klist 'list'. Currently, struct klist
contained only SLIST_HEAD as its member, thus sizeof(struct klist) would
equal to sizeof(struct klist *), so this change makes the code more
correct in terms of semantics, but should be a no-op to compiler at this
time.
