Hi all,

Today's linux-next merge of the ceph tree got a conflict in:

  fs/ceph/inode.c

between commit:

  c453bdb53534 ("ceph: convert to new timestamp accessors")

from Linus' tree and commit:

  38d46409c463 ("ceph: print cluster fsid and client global_id in all debug=
 logs")

from the ceph 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.

--=20
Cheers,
Stephen Rothwell
