+Description: System hang on startup
+Details    : This bug allowed the liblustre (e.g. catamount) client to
+             return to the app before handling all startup RPCs.  This
+            could leave the node unresponsive to lustre network traffic
+            and manifested as a server ptllnd timeout.

+            boolean to control whether to print peer debug info when a

+Description: large O_DIRECT requests fail under memory pressure/fragmentation
+Details    : Large single O_DIRECT read and write calls can fail to allocate
+            a sufficiently large buffer to process the request.  In case of
+            allocation failure the allocation is retried with a smaller
