Subject[PATCH v2] Adding smp_acquire__after_ctrl_dep barrier
Changes in v2:
- hopefully fixed all (at least to my eye and to checkpatch)
errors on whitespacing, etc.
- changed text on ACQUIRE guarantees pointed by Andrea and
- removed mentioning of control dependency on dec/sub_and_test

I also have to send it now with a cover letter, because I think
it is Intel mailer that malformed the patch last time for god knows
what reason...

Elena Reshetova (1):
refcount_t: add ACQUIRE ordering on success for dec(sub)_and_test
