Description Alasdair Kergon 2006-03-20 14:25:12 EST
The code that handles bios that span table target boundaries by breaking
them up into smaller bios will not split an individual struct bio_vec
into more than two pieces.  Sometimes more than that are required.
This patch adds a loop to break the second piece up into as many
pieces as are necessary.

committed in stream u4 build 34.9. A test kernel with this patch is available
