| |
Hi Neil,
Today's linux-next merge of the md tree got a conflict in fs/bio.c between commit 4363ac7c13a9 ("block: Implement support for WRITE SAME") from the block tree and commit 368e564836d3 ("block: makes bio_split support bio without data") from the md tree.
I fixed it up (I think - see below) and can carry the fix as necessary (no action is required).
