We were planning to send this patch series via ext4 tree.
But it seems this might conflict with the below mentioned patches sitting in
linux-next. So let me rebase my patches on top of these and maybe hold to this
series until the current set of changes land in linux tree to avoid any merge
conflicts later.
But either ways do let me know if you would like to take any other preferred
route. Since this is not critical, so I am fine with either ways you suggest.

fs/buffer: Combine two submit_bh() and ll_rw_block() arguments
Both submit_bh() and ll_rw_block() accept a request operation type and
request flags as their first two arguments. Micro-optimize these two
functions by combining these first two arguments into a single argument.
This patch does not change the behavior of any of the modified code.
