From 864bdb3b6cbd9911222543fef1cfe36f88183f44 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 22 Aug 2012 18:42:10 -0400 Subject: new helper: daemonize_descriptors() descriptor-related parts of daemonize, done right. As the result we simplify the locking rules for ->files - we hold task_lock in *all* cases when we modify ->files.
