2015-11-06mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIMMel Gorman2-2/+2
__GFP_WAIT was used to signal that the caller was in atomic context and could not sleep. Now it is possible to distinguish between true atomic context and callers that are not willing to sleep. The latter should clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing __GFP_WAIT behaves differently, there is a risk that people will clear the wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly indicate what it does -- setting it allows all reclaim activity, clearing them prevents it.

2015-10-27staging/rdma/hfi1: Prevent silent data corruption with user SDMAMitko Haralanov1-38/+52
User SDMA keeps track of progress into the submitted IO vectors by tracking an offset into the vectors when packets are submitted. This offset is updated after a successful submission of a txreq to the SDMA engine. The same offset was used when determining whether an IO vector should be 'freed' (pages unpinned) in the SDMA callback functions. This was causing a silent data corruption in big jobs (> 2 nodes, 120 ranks each) on the receive side because the send side was mistakenly unpinning the vector pages before the HW has processed all descriptors referencing the vector.
