Hi Al,
Today's linux-next build (x86_64_allmodconfig) produced this warning:
fs/ceph/super.c:216: warning: initialization from incompatible pointer type
Introduced by commit bc39e28236344af617473df80abb7de43176511e ("pass
writeback_control to ->write_inode") from the vfs tree interacting with
commit 16725b9d2a2e3d0fd2b0034482e2eb0a2d78050f ("ceph: super.c") from
the ceph tree.
This will need a fixup patch (see below) which I can carry in the
linux-next tree. There may, of course, be a better fix (which I can
carry if someone sends it to me).
