Hello Alexander/Andrey/Dmitry/Reviewers,
Submitting v3 for your review/consideration. First patch provides more
reliable double-free detection for KASAN. Second patch provides new
double-free tests for 'test_kasan'.
Major changes from v2:
o object lock/unlock simplified to use generic bit spinlock apis instead of
custom CAS loop. A 'safety valve' is provided for lock in case an
out-of-bounds write flips lock bit.
o test_kasan concurrent double-free test simplified to use
on_each_cpu_mask() instead of custom threads.
v2 link: https://lkml.org/lkml/2016/5/6/210
Patchset is based on linux-next 'next-20160524'.
Thanks,
Kuthonuzo
