[GET PULL] ext4 updates for 3.16

[Theodore Ts'o <tytso@mit.edu>]

A fairly minor obvious merge fix will be required due to a conflicting
change to a comment made by a commit already in your tree:

 -       * Comments copied from block_write_full_page_endio:
++       * Comments copied from block_write_full_page:

coupled with a move of the code in question in the ext4 tree.

Thanks!!
