New writeback changes in 4.2-RC1 have exposed that we incorrectly set page_writeback on a page that is being written synchronously, which aside from this new crash (dereference of NULL inode->i_wb from set_page_writeback) likely threw off some related page statistics in the past.

A space has been inserted between two concatenated strings as required from checkpatch.pl These two updates do not lead to any problem as DFID is defined as a string in ./drivers/staging/lustre/lustre/include/lustre/lustre_user.h The script checkpatch.pl does not return any other warning/error.
