Re: [PATCH] block: reopen the device in blkdev_reread_part

Historically the BLKRRPART ioctls called into the now defunct ->revalidate

When the ->revalidate method was removed this revalidation was lost,
leading to lots of I/O errors when using the eject command.  Fix this by
reopening the device to rescan the partitions, and thus calling the
revalidation logic in the sd driver.

It looks like a related issue that I've reported in [1].  And this looks
much better!
