Hi,
As of now, the performance xlators cache the data and perform some
optimizations for all the fops irrespective of whether the fop is
generated from the application or internal xlator. I think, performance
xlators should come in to picture for only the fops generated by the
applications. Imagine the situation where a graph change happens and
fuse xlator sends open call on the fds to migrate them to the new graph.
But the open call might not reach posix if open-behind unwinds success
to fuse xlator.
It can be done in 2 ways.
1) Set a key in dictionary if the call is generated internally
OR
2) Set a flag in the callstack itself, whether the fop is internal fop
or generated from the application.
Please provide feedback.
