bl, stripeno and objsetno should be u64 -- otherwise large enough files get corrupted. How large depends on file layout: - 4M-objects layout (default): any file over 16P - 64K-objects layout (smallest possible object size): any file over 512T Only CephFS is affected, rbd doesn't use ceph_calc_file_object_mapping() yet. Fortunately, CephFS has a max_file_size configurable, the default for which is way below both of the above numbers. Reimplement the logic from scratch with no layout validation -- it's done on the MDS side. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Alex Elder <elder@linaro.org>
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.
