linux-stable.git/fs/proc/self.c, branch v3.8 Linux kernel stable tree procfs: Use the proc generic infrastructure for proc/self. 2012-11-19T11:09:34+00:00 Eric W. Biederman ebiederm@xmission.com 2010-07-10T21:52:49+00:00 e656d8a6f7fdf7612d2f5771f0ddfca9487f59d9 I had visions at one point of splitting proc into two filesystems. If that had happened proc/self being the the part of proc that actually deals with pids would have been a nice cleanup. As it is proc/self requires a lot of unnecessary infrastructure for a single file. The only user visible change is that a mounted /proc for a pid namespace that is dead now shows a broken proc symlink, instead of being completely invisible. I don't think anyone will notice or care.
