[PATCH 4.10 035/167] staging/lustre/lnet: Fix allocation size for sv_cpt_data

From: Greg Kroah-Hartman
Date: Fri Mar 10 2017 - 04:28:54 EST

4.10-stable review patch. If anyone has any objections, please let me know.


From: Oleg Drokin <green@xxxxxxxxxxxxxx>

commit dc7ffefdcc28a45214aa707fdc3df6a5e611ba09 upstream.

This is unbreaking another of those "stealth" janitor
patches that got in and subtly broke some things.

sv_cpt_data is a pointer to pointer, so need to
dereference it twice to allocate the correct structure size.

Fixes: 9899cb68c6c2 ("Staging: lustre: rpc: Use sizeof type *pointer instead of sizeof type.")
