From 356d6d5058c8082b9e811838ab2fa27825c947e4 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 16 Oct 2007 23:27:23 -0700 Subject: [PATCH] exec: consolidate 2 fast-paths Now that we don't pre-allocate the new ->sighand, we can kill the first fast path, it doesn't make sense any longer. At best, it can save one "list_empty()" check but leads to the code duplication.
