David Howells 94817712b5 ocfs2: Fix use of slab data with sendpage ... [ Upstream commit 86d7bd6e66 ] ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and o2net_keep_resp and then passes these to sendpage. This isn't really allowed as the lifetime of slab objects is not controlled by page ref - though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES will, however, print a warning and give an error. Fix it to use folio_alloc() instead to allocate a buffer for the handshake message, keepalive request and reply messages.
