Subject: staging: lustre: ptlrpc: kfree used instead of kvfree
From: Nadav Amit <redacted>
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.
