From 4984037bef54253d4d010d3e57f175ab694bee26 Mon Sep 17 00:00:00 2001 From: Vipul Pandya Date: Fri, 18 May 2012 15:29:29 +0530 Subject: RDMA/cxgb4: Disable interrupts in c4iw_ev_dispatch() Use GFP_ATOMIC in _insert_handle() if ints are disabled. Don't panic if we get an abort with no endpoint found. Just log a warning.
