In sst_prepare_and_post_msg(), when a response is received in "block", the following code gets executed:
*data = kzalloc(block->size, GFP_KERNEL); memcpy(data, (void *) block->data, block->size);
Yuck, thanks.
Julia, Dan, could cocci or smatch help find any other similar misuses here?

I tried the following semantic patch, that is quite general, and the fixed issue was the only report.
@@ expression x,y,sz; identifier f,g; @@
- *x = f(sz,...);
...
- g(x,y,sz);
Hi Julia,
This would find exactly the same form, but I think the question is are there assignments of a **pp that should have been *pp
Something like:
@@ type P; P **pp; @@
- pp = <alloc>|<copy>|<access>(..., sizeof(P), ...)
I didn't get anything for this. Did you mean for the left hand side of the assignment to be pp or *pp? Is the issue that the type is wrong?
