Description

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix memleak for 'conf->bio_split' In the error path of raid10_run(), 'conf' need be freed, however, 'conf->bio_split' is missed and memory will be leaked. Since there are 3 places to free 'conf', factor out a helper to fix the problem.
