undo LVM change from merge

Linus, Alan, Al,
it appears that when merging Alan's updated LVM code into mainline, it reverted a change (from Al to avoid race conditions with block device modules, I think). The patch fragment below should be re-applied:

@@ -400,6 +400,7 @@
/* block device operations structure needed for 2.3.38? and above */ struct block_device_operations lvm_blk_dops =
{

+       owner:          THIS_MODULE,
        open:           lvm_blk_open,
        release:        lvm_blk_close,
        ioctl:          lvm_blk_ioctl,

It isn't in the LVM CVS yet, but if it should be I will put it there so we don't lose it again.

Cheers, Andreas
