Jeff Layton 5eb9f6040f ceph: do a LOOKUP in d_revalidate instead of GETATTR 
In commit c3f4688a08 (ceph: don't set req->r_locked_dir in
ceph_d_revalidate), we changed the code to do a GETATTR instead of a
LOOKUP as the parent info isn't strictly necessary to revalidate the
dentry. What we missed there though is that in order to update the lease
on the dentry after revalidating it, we _do_ need parent info.

Change ceph_d_revalidate back to doing a LOOKUP instead of a GETATTR so
that we can get the parent info in order to update the lease from
ceph_fill_trace. Note that we set req->r_parent here, but we cannot set
the CEPH_MDS_R_PARENT_LOCKED flag as we can't guarantee that it is.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
