[linux-lvm] Problems(?) with pvresize

I've got a similar problem to the one reported earlier in June by Peter 

I've got a hardware-raid5 that I've extended (/dev/sdk), and after 
extending it, I get the kernel to recognize the new size.
But pvresize is still using the old size. I'm pretty convinced that a 
reboot will solve this issue for me, but isn't there a way
of solving this without rebooting?

$ cat /sys/block/sdk/size

# blockdev --getsz /dev/sdk

# pvresize -v -d /dev/sdk
    Using physical volume(s) on command line
    Wiping cache of LVM-capable devices
    Archiving volume group "vg01" metadata (seqno 123).
    No change to size of physical volume /dev/sdk.
    Resizing volume "/dev/sdk" to 3906166400 sectors.
    Updating physical volume "/dev/sdk"
    Creating volume group backup "/etc/lvm/backup/vg01" (seqno 124).
  Physical volume "/dev/sdk" changed
  1 physical volume(s) resized / 0 physical volume(s) not resized
