docs/memory-barriers.txt: Fix a typo in CPU MEMORY BARRIERS section
Commit 39323c6 ("smp_mb__{before,after}_atomic(): update Documentation")
has a typo in CPU MEORY BARRIERS section:
"RMW functions that do not imply are memory barrier are ..." should be
"RMW functions that do not imply a memory barrier are ...".
This patch fixes this typo.

Examples for atomic - RMW functions that do not imply are memory barrier are e.g. add, + RMW functions that do not imply a memory barrier are e.g. add, subtract, (failed) conditional operations, _relaxed functions, but not atomic_read or atomic_set. A common example where a memory barrier may be required is when atomic ops are used for reference |
