ceph: disable updating the atime since cephfs won't maintain it
Since CephFS makes no attempt to maintain atime, we shouldn't try to update it in mmap and generic read cases and ignore updating it in direct and sync read cases. And even we update it in mmap and generic read cases we will drop it and won't sync it to MDS. And we are seeing the atime will be updated and then dropped to the floor again and again.

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.
