From c4a2d7fbec3029c8891a3ad5fceec2992096a3b7 Mon Sep 17 00:00:00 2001 From: Michael Halcrow Date: Fri, 4 Jul 2008 09:59:35 -0700 Subject: [PATCH] ecryptfs: remove unnecessary mux from ecryptfs_init_ecryptfs_miscdev() The misc_mtx should provide all the protection required to keep the daemon hash table sane during miscdev registration. Since this mutex is causing gratuitous lockdep warnings, this patch removes it.
