Hi Al,
Today's linux-next merge of the vfs tree got a conflict in
fs/ext4/symlink.c between commit fd64e6fd4575 ("ext4 crypto: reorganize
how we store keys in the inode") from the ext4 tree and commits
5542f03602af ("ext4: split inode_operations for encrypted symlinks off
the rest") and cf41cea5a829 ("new ->follow_link() and ->put_link()
calling conventions") from the vfs tree.
I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).
