From 1539d584e488538451526da039fa554fdeea1177 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 10 Apr 2018 16:31:57 -0700 Subject: [PATCH] proc: register filesystem last As soon as register_filesystem() exits, filesystem can be mounted. It is better to present fully operational /proc. Of course it doesn't matter because /proc is not modular but do it anyway. Drop error check, it should be handled by panicking.
