History
Konstantin Belousov 6272798a3f Both vn_close() and VFS_PROLOGUE() evaluate vp->v_mount twice, without 
holding the vnode lock; vp->v_mount is checked first for NULL
equiality, and then dereferenced if not NULL.  If vnode is reclaimed
meantime, second dereference would still give NULL.  Change
VFS_PROLOGUE() to evaluate the mp once, convert MNTK_SHARED_WRITES and
MNTK_EXTENDED_SHARED tests into inline functions.
