Hi Jens,
Today's linux-next merge of the block tree got a conflict in:
fs/f2fs/data.c
between commits:
19a5f5e2ef37 ("f2fs: drop any block plugging")
52763a4b7a21 ("f2fs: detect host-managed SMR by feature flag")
78682f794479 ("f2fs: fix to avoid reading out encrypted data in page cache")
from the f2fs tree and commits:
4e49ea4a3d27 ("block/fs/drivers: remove rw argument from submit_bio")
04d328defd06 ("f2fs: use bio op accessors")
from the block tree.
I fixed it up (see below - I am not confident of these fixups, so
please check and let me know if anything else is needed) 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.
