Subject: linux-next: manual merge of the akpm-current tree with the vfs tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
fs/autofs4/inode.c between commit baa40671d3e3 ("autofs4: make freeing
sbi rcu-delayed") from the vfs tree and commit e4af471815fc ("autofs4:
allow autofs to work outside the initial PID namespace") from the
akpm-current tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
