Hi, the previous version of the patchset has been posted here [1]. kbuild robot found some compilation issues which are fixed here. Vlastimil has reviewed the patchset and his review feedback has been addressed I believe. No other changes were introduced in this version and I believe this should be ready to be merged. Original cover: This is a long overdue and I am really sorry about that. I just didn't get to sit and come up with this earlier as there was always some going on which preempted it. This patchset adds two tracepoints which should help us to debug oom decision making. The first one is placed in should_reclaim_retry and it tells us why do we keep retrying the allocation and reclaim while the second is in should_compact_retry which tells us the similar for the high order requests. In combination with the existing compaction and reclaim tracepoints we can draw a much better picture about what is going on and why we go and declare the oom. I am not really a tracepoint guy so I hope I didn't do anything obviously stupid there. Thanks to Vlastimil for his help before I've posted this. Anywa feedback is of course welcome!
