From 796a6b521d0eadb338adf8cf7e482351c3a8a7b4 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 16 Jan 2010 13:28:47 -0500 Subject: Kill CL_PROPAGATION, sanitize fs/pnode.c:get_source() First of all, get_source() never results in CL_PROPAGATION alone. We either get CL_MAKE_SHARED (for the continuation of peer group) or CL_SLAVE (slave that is not shared) or both (beginning of peer group among slaves). Massage the code to make that explicit, kill CL_PROPAGATION test in clone_mnt() (nothing sets CL_MAKE_SHARED without CL_PROPAGATION and in clone_mnt() we are checking CL_PROPAGATION after we'd found that there's no CL_SLAVE, so the check for CL_MAKE_SHARED would do just as well). Fix comments, while we are at it...
