Hi all,
Today's linux-next merge of the notifications tree got a conflict in:
fs/mount.h
between commit:
9f6c61f96f2d ("proc/mounts: add cursor")
from the vfs tree and commit:
cd7109637b0b ("watch_queue: Implement mount topology and attribute change notifications")
from the notifications 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,

Hi all,
Today's linux-next merge of the notifications tree got a conflict in:
include/linux/pipe_fs_i.h
between commit:
f6dd975583bd ("pipe: merge anon_pipe_buf*_ops")
from the vfs tree and commits:
8cfba76383e9 ("pipe: Allow buffers to be marked read-whole-or-error for notifications")
e7d553d69cf6 ("pipe: Add notification lossage handling")
from the notifications 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.
