Hi Miklos,
Today's linux-next merge of the overlayfs tree got a conflict in:
fs/btrfs/ioctl.c
between commit:
0b4dc087e29a ("Btrfs: dedupe_file_range ioctl: remove 16MiB restriction")
from the btrfs-kdave tree and commits:
83d499febfac ("vfs: dedpue: return loff_t")
7765f19ed5f9 ("vfs: dedupe: rationalize args")
from the overlayfs tree.
[I note the typo in the subject of commit 83d499febfac]
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.
