[linux-lvm] kernel-Oops in 2.4.19 with LVM-1.0.5 + devfs

[kaoru at bsd.tnes.nec.co.jp]

Hi,

When I executed the following commands, I get oops 
running under 2.4.19-rc3 kernel with LVM-1.0.5 + devfs.

# lvrename /dev/vg11/lv11_01 /dev/vg11/lv11_01new
# vgdisplay -v vg11

I executed "cat /proc/partitions" instead of "vgdisplay",
oops occurred, too. 

I think that the cause of this is the return value of 
lvm_fs_create_lv() is ignored which is called within 
a lvm_do_lv_rename function.

I made the following patch for this problem, and it seems 
to work. Any comments?
