From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
In recent tests of the O_DIRECT code, a number of bugs were discovered
in the error codepaths, some of which were shown to result in data
corruption. The tests involved using pNFS flexfiles with 3-way
mirroring, and then shutting down one of the data servers. When the data
was later re-read from the server, it was shown to not match the
original data.
