From c9da99e6475f92653139e43f3c30c0cd011a0fd8 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 30 Dec 2011 00:54:39 +0000 Subject: [PATCH] unix_diag: Fixup RQLEN extension report While it's not too late fix the recently added RQLEN diag extension to report rqlen and wqlen in the same way as TCP does. I.e. for listening sockets the ack backlog length (which is the input queue length for socket) in rqlen and the max ack backlog length in wqlen, and what the CINQ/OUTQ ioctls do for established.
