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

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

 



Hi Shaohua,

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

  drivers/md/raid5.c

between commit:

  48920ff2a5a9 ("block: remove the discard_zeroes_data flag")

from the block tree and commit:

  97d53438081e ("Revert "md/raid5: limit request size according to implementation limits"")

from the md 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.
