Subjectlinux-next: manual merge of the btrfs-kdave tree with Linus' tree
Hi David,

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

fs/btrfs/inode.c

between commit:

58efbc9f5463 ("Btrfs: fix blk_status_t/errno confusion")

from Linus' tree and commit:

e6961cac730f ("btrfs: Move skip checksum check from btrfs_submit_direct to __btrfs_submit_dio_bio")

from the btrfs-kdave 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.

Cheers,
Stephen Rothwell
