Title
svcrdma: use rc_pageoff for memcpy byte offset
Summary
In the Linux kernel, the following vulnerability has been resolved: svcrdma: use rc_pageoff for memcpy byte offset svc_rdma_copy_inline_range added rc_curpage (page index) to the page base instead of the byte offset rc_pageoff. Use rc_pageoff so copies land within the current page. Found by ZeroPath (https://zeropath.com)
