This is my second attempt to have an initial set of ceph-specific tests merged into fstests. In this patchset I'm pushing a different set of tests, focusing on the copy_file_range testing, although I *do* plan to get back to the quota tests soon. This syscall has a few peculiarities in ceph as it is able to use remote object copies without the need to download/upload data from the OSDs. However, in order to take advantage of this remote copy, the copy ranges and sizes need to include at least one object. Thus, all the currently existing generic tests won't actually take advantage of this feature. Let me know any comments/concerns about this patchset. Also note that currently, in order to have cephfs copy_file_range to take advantage of remote object copies, the additional 'copyfrom' mount parameter is required; if not used, the copy will fallback to the default VFS implementation. (Hopefully this additional param will be dropped in the future.) Changes since v1: - New _ceph_create_file_layout() function (in common/ceph) that creates and sets the file layout - Added commit IDs relevant to tracker issue#37378 (test 002) - Fixed tests file mode to 755 (Also clarified cover-letter text regarding the 'copyfrom' usage.)
