linux-next: manual merge of the scsi tree with the block tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the scsi tree got a conflict in:

  block/blk-merge.c

between commit:

  6928b8f7eafa ("block: remove the per-bio/request write hint")

from the block tree and commit:

  73bd66d9c834 ("scsi: block: Remove REQ_OP_WRITE_SAME support")

from the scsi tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
