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

Pranith Kumar (9):
doc: memory-barriers.txt: Document use of lockless_dereference()
drivers: dma: Replace smp_read_barrier_depends() with
lockless_dereference()
dcache: Replace smp_read_barrier_depends() with lockless_dereference()
hyperv: Replace smp_read_barrier_depends() with lockless_dereference()
percpu: Replace smp_read_barrier_depends() with lockless_dereference()
perf: Replace smp_read_barrier_depends() with lockless_dereference()
seccomp: Replace smp_read_barrier_depends() with
lockless_dereference()
task_work: Replace smp_read_barrier_depends() with
lockless_dereference()
netfilter: Replace smp_read_barrier_depends() with
lockless_dereference()
