From 860fbbc343bf05a71b31555579ff4878194be01b Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 29 Apr 2016 14:16:51 -0700 Subject: [PATCH] sctp: prepare for socket backlog behavior change sctp_inq_push() will soon be called without BH being blocked when generic socket code flushes the socket backlog. It is very possible SCTP can be converted to not rely on BH, but this needs to be done by SCTP experts. Signed-off-by: Eric Dumazet Acked-by: Marcelo Ricardo Leitner Signed-off-by: David S.
