Re: kern/36150 (vnlock deadlock on nbftp due to layerfs and LFS interaction)

Synopsis: vnlock deadlock on nbftp due to layerfs and LFS interaction

Is lfs_putpages significantly different from genfs_putpages in this regard?
genfs_putpages flips locks on and off like beads on an abacus, including
the uvm_object lock (which for vnodes I thought was the same as the vnode
lock, but maybe not) and I've long thought it problematic but had no useful
ideas about how to change it.
