Problem Description:

=============================================
[ INFO: possible recursive locking detected ]
2.6.23-rc8-mm2 #101
---------------------------------------------
beagled/3680 is trying to acquire lock:
 (&sb->s_type->i_mutex_key#6){--..}, at: [<c02bd867>] mutex_lock+0x1c/0x1f
but task is already holding lock:
 (&sb->s_type->i_mutex_key#6){--..}, at: [<c02bd867>] mutex_lock+0x1c/0x1f
other info that might help us debug this:
3 locks held by beagled/3680:
 #0:  (&sb->s_type->i_mutex_key#6){--..}, at: [<c02bd867>] mutex_lock+0x1c/0x1f
 #1:  (&REISERFS_I(inode)->xattr_sem){--..}, at: [<e18f41bc>]
reiserfs_setxattr+0x4f/0xf6 [reiserfs]  #2: 
(&REISERFS_SB(s)->xattr_dir_sem){----}, at: [<e18f41db>]
reiserfs_setxattr+0x6e/0xf6 [reiserfs]

 =======================

Steps to reproduce:

- mount -t reiserfs -o noatime,nodiratime,user_xattr
/dev/mapper/vglinux1-lvhome  /home
- log in the gnome desktop, this will launch beagled
