| Subject | linux-next: manual merge of the f2fs tree with the ext4 tree |
| Message-ID | <rwGsN-8t5-1@gated-at.bofh.it> |
Hi Jaegeuk,
Today's linux-next merge of the f2fs tree got a conflict in:
fs/ext4/ext4.h
between commit:
c8585c6fcaf2 ("ext4: fix races between changing inode journal mode and ext4_writepages")
from the ext4 tree and commit:
a618a2a1dda4 ("ext4 crypto: migrate into vfs's crypto engine")
from the f2fs 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.
P.S. I would expect to see a Reviewed-by or Acked-by from the ext4
maintainer on that f2fs tree commit ...

Cheers,
Stephen Rothwell

Hi Stephen,
Thank you for the notice.
I've been waiting for a comment about the below patch targeted to v4.7 from Ted.
Meanwhile, I intended to prepare -next for that patch in advance.
Surely, once I get a sense that I need to consider v4.8, I'll drop this patch
for -next right away.
Thanks,
