SVN rev 187887 on 2009-01-29 11:03:57Z by kib
MFC r186560:
After the pfs_vncache_mutex is dropped, another thread may attempt to
do pfs_vncache_alloc() for the same pfs_node and pid. In this case, we
could end up with two vnodes for the pair. Recheck the cache under the
locked pfs_vncache_mutex after all sleeping operations are done.
Do not call free() on the struct pfs_vdata after insmntque() failure,
because vp->v_data points to the structure, and pseudofs_reclaim()
frees it by the call to pfs_vncache_free().
MFC r186981 (by marcus):
vput the vnode.
