[PATCH 0/7] staging: lustre: last missing patches for lustre 2.6

Resolved the last remain bug that prevented earlier submission. This covers the remaining patches that were missing from the upstream client that was in Lustre 2.6 except for the work for LU-2484. The work for LU-2484 depends on the stat infrastructure that was removed earlier from the upstream cli

The "broken in pipe" handler of the USB-HDM calls most_stop_enqueue() to stop the MBO traffic before returning all MBOs back to the Mostcore. As the enqueue() call from the Mostcore may run in parallel with the most_stop_enqueue(), the HDM may run into the inconsistent state and crash the kernel.
