[PATCH v2 2/4] nvme-tcp: use sendpages_ok() instead of sendpage_ok()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
