This patch re-organizes copy_file_range, trying to fix a few issues in the error handling. Here's the summary: - Abort copy if initial do_splice_direct() returns fewer bytes than requested. - Move the 'size' initialization (with i_size_read()) further down in the code, after the initial call to do_splice_direct(). This avoids issues with a possibly stale value if a manual copy is done. - Move the object copy loop into a separate function. This makes it easier to handle errors (e.g, dirtying caps and updating the MDS metadata if only some objects have been copied before an error has occurred). - Added calls to ceph_oloc_destroy() to avoid leaking memory with src_oloc and dst_oloc - After the object copy loop, the new file size to be reported to the MDS (if there's file size change) is now the actual file size, and not the size after an eventual extra manual copy. - Added a few dout() to show the number of bytes copied in the two manual copies and in the object copy loop.
