Subject[PATCH RFC tools/lkmm 08/12] memory-barriers: Fix description of data dependency barriers
Date
From: Nikolay Borisov <nborisov@suse.com>

In the description of data dependency barriers the words 'before' is
used erroneously. Since such barrier order dependent loads one after
the other. So substitute 'before' with 'after'.

@@ -400,7 +400,7 @@ Memory barriers come in four basic varieties:
where two loads are performed such that the second depends on the result
of the first (eg: the first load retrieves the address to which the second
load will be directed), a data dependency barrier would be required to
- make sure that the target of the second load is updated before the address
+ make sure that the target of the second load is updated after the address
obtained by the first load is accessed.

A data dependency barrier is a partial ordering on interdependent loads
