linux-next: manual merge of the vfs tree with the tree

[michael@ozlabs.org (mpe@ellerman.id.au)]

Hi Al,

Today's linux-next merge of the vfs tree got a conflict in fs/namei.c between
commit 890458a43dbd ("path: New helpers path_get_pin/path_put_unpin for path
pin") from the nfsd tree and commit 894bc8c4662b ("namei: remove restrictions
on nesting depth") from the vfs tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

cheers
