From 2c3682f0be97a5f57c6c8b40fa154dfc77efb461 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Sun, 18 Mar 2018 12:56:49 -0700 Subject: sock: make static tls function alloc_sg generic sock helper The TLS ULP module builds scatterlists from a sock using page_frag_refill(). This is going to be useful for other ULPs so move it into sock file for more general use. In the process remove useless goto at end of while loop. Signed-off-by: John Fastabend Acked-by: David S.
