From 7a9461939a46345860622ea36ff267ee4446f00f Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Mon, 6 Apr 2009 19:01:53 -0700 Subject: [PATCH] nilfs2: use unlocked_ioctl Pekka Enberg suggested converting ->ioctl operations to use ->unlocked_ioctl to avoid BKL. The conversion was verified to be safe, so I will take it on this occasion.
