However, the structures on these two lists are not the same. The wait_list references struct ib_mad_send_wr_private, but local_list references struct ib_mad_local_private. Cancel_mads() treats all items moved to the cancel_list as struct ib_mad_send_wr_private. This leads to a system crash when requests are moved from the local_list to the cancel_list. Fix this by leaving local_list alone. All requests on the local_list have completed are just awaiting processing by a queued worker thread. Bug (crash) reported by Dotan Barak . Problem with local_list access reported by Robert Reynolds . Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier --- Reading git-diff-tree failed
