SVN rev 202814 on 2010-01-22 17:02:07Z by jhb
MFC 193951:
Adapt vfs kqfilter to the shared vnode lock used by zfs write vop. Use
vnode interlock to protect the knote fields. The locking assumes
that shared vnode lock is held, thus we get exclusive access to knote
either by exclusive vnode lock protection, or by shared vnode lock +
vnode interlock.
Unlike the change in HEAD, this does not remove kl_locked() and replace it
with kl_assert_locked() and kl_assert_unlocked(). Instead, the kl_locked
can now be set to NULL in which case no assertion checks are performed on
the lock. The vfs kqfilter code uses this mode to disable assertion checks.
This preserves the existing ABI for knlist_init().
Add convenience function knlist_init_mtx to reduce number of arguments
for typical knlist initialization.
