[PATCH v2 0/9] Replace smp_read_barrier_depends() with lockless_derefrence()

[Pranith Kumar]

Recently lockless_dereference() was added which can be used in place of
hard-coding smp_read_barrier_depends(). 

http://lkml.iu.edu/hypermail/linux/kernel/1410.3/04561.html

The following series tries to do this.

There are still some hard-coded locations which I was not sure how to replace
with. I will send in separate patches/questions regarding them.
