With EC overwrites maturing, the kernel client will be getting exposed to potentially very wide EC pools. While "min(pi->size, X)" works fine when the cluster is stable and happy, truncating OSD sets interferes with resend logic (ceph_is_new_interval(), etc). Abort the mapping if the pool is too wide, assigning the request to the homeless session. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Sage Weil <sage@redhat.com>
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.
