From 31e54b01f3f00b595aac02e887960e5dcc575844 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 13 Aug 2009 12:18:08 +0100 Subject: GFS2: Add sysfs link to device This adds a link from the per-gfs2 sb sysfs directory to the block device upon which the filesystem is mounted. The link is called "device", strangely enough :-) Signed-off-by: Steven Whitehouse --- fs/gfs2/sys.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/fs/gfs2/sys.c b/fs/gfs2/sys.c index dda4bf1e9eb..0d4f7e974e9 100644 --- a/fs/gfs2/sys.c +++ b/fs/gfs2/sys.c @@ -16,6 +16,7 @@ #include #include #include +#include #include "gfs2.h" #include "incore.h" @@ -542,9 +543,17 @@ int gfs2_sys_fs_add(struct gfs2_sbd *sdp) if (error) goto fail_tune; + error = sysfs_create_link(&sdp->sd_kobj, + &disk_to_dev(sb->s_bdev->bd_disk)->kobj, + "device"); + if (error) + goto fail_lock_module; + kobject_uevent_env(&sdp->sd_kobj, KOBJ_ADD, envp); return 0; +fail_lock_module: + sysfs_remove_group(&sdp->sd_kobj, &lock_module_group); fail_tune: sysfs_remove_group(&sdp->sd_kobj, &tune_group); fail_reg: @@ -556,6 +565,7 @@ fail: void gfs2_sys_fs_del(struct gfs2_sbd *sdp) { + sysfs_remove_link(&sdp->sd_kobj, "device"); sysfs_remove_group(&sdp->sd_kobj, &tune_group); sysfs_remove_group(&sdp->sd_kobj, &lock_module_group); kobject_put(&sdp->sd_kobj); -- cgit v1.2.3
