From 8082d36aed26c4fb6ed43e4008303682eabf839e Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Mon, 6 Apr 2009 19:01:53 -0700 Subject: nilfs2: remove compat ioctl code This removes compat code from the nilfs ioctls and applies the same function for both .ioctl and .compat_ioctl file operations.
