From 6af7331a70b4888df43ec1d7e1803ae2c43b6981 Mon Sep 17 00:00:00 2001 From: Ofir Gal Date: Thu, 18 Jul 2024 11:45:13 +0300 Subject: nvme-tcp: use sendpages_ok() instead of sendpage_ok() Currently nvme_tcp_try_send_data() use sendpage_ok() in order to disable MSG_SPLICE_PAGES, it check the first page of the iterator, the iterator may represent contiguous pages. MSG_SPLICE_PAGES enables skb_splice_from_iter() which checks all the pages it sends with sendpage_ok(). When nvme_tcp_try_send_data() sends an iterator that the first page is sendable, but one of the other pages isn't skb_splice_from_iter() warns and aborts the data transfer. Using the new helper sendpages_ok() in order to disable MSG_SPLICE_PAGES solves the issue.
