If anyone has any objections, please let me know. ------------------ From: Nadav Amit commit c3eec59659cf25916647d2178c541302bb4822ad upstream. rq_reqbuf is allocated using kvmalloc() but released in one occasion using kfree() instead of kvfree(). The issue was found using grep based on a similar bug.
