Hi all, Today's linux-next merge of the fscache tree got a conflict in: fs/cachefiles/bind.c between commit: bb49e9e730c2 ("fs: add is_idmapped_mnt() helper") from the pidfd tree and commit: d18c9010376b ("cachefiles: Delete the cachefiles driver pending rewrite") from the fscache tree. I fixed it up (the latter deleted the file, so I did that and then added the following patch) 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.
