From 9df5778ecee8b301b447fc05706792d5f447ace5 Mon Sep 17 00:00:00 2001 From: Tristan Ye Date: Tue, 2 Mar 2010 13:59:42 +0800 Subject: Ocfs2: Move ocfs2 ioctl definitions from ocfs2_fs.h to newly added ocfs2_ioctl.h Currently we were adding ioctl cmds/structures for ocfs2 into ocfs2_fs.h which was used for define ocfs2 on-disk layout. That sounds a little bit confusing, and it may be quickly polluted espcially when growing the ocfs2_info_request ioctls afterwards(it will grow i bet). As a result, such OCFS2 IOCs do need to be placed somewhere other than ocfs2_fs.h, a separated ocfs2_ioctl.h will be added to store such ioctl structures and definitions which could also be used from userspace to invoke ioctls call.
