    Subject[PATCH 4.4 40/43] staging: lustre: ptlrpc: kfree used instead of kvfree
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Nadav Amit <namit@vmware.com>

    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.

    Fixes: d7e09d0397e8 ("add Lustre file system client support")
    Fixes: ee0ec1946ec2 ("lustre: ptlrpc: Replace uses of OBD_{ALLOC,FREE}_LARGE")
