If a create is done, then typically we'll end up writing to the file soon afterward. We don't want to wait for the reply before doing that when doing an async create, so that means we need the layout for the new file before we've gotten the response from the MDS. All files created in a directory will initially inherit the same layout, so copy off the requisite info from the first synchronous create in the directory, and save it in a new i_cached_layout field. Zero out the layout when we lose Dc caps in the dir. Signed-off-by: Jeff Layton <jlayton@kernel.org> Reviewed-by: "Yan, Zheng" <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
