[PATCH] btrfs: mask out gfp flasg in releasepage
btree_releasepage is a callback and can be passed unknown gfp flags and then they may end up in kmem_cache_alloc called from alloc_extent_state, slab allocator will BUG_ON when there is HIGHMEM or DMA32 flag set. This may happen when btrfs is mounted from a loop device, which masks out __GFP_IO flag. The check in try_release_extent_state 3399 if ((mask & GFP_NOFS) ==

[PATCH v2 0/2] drm/ttm: Add an option to report graphics memory OOM
Some graphics APIs differentiate between out-of-graphics-memory and out-of-host-memory (system memory). Add a device init flag to have -ENOSPC propagated from the resource managers instead of being converted to -ENOMEM, to aid driver stacks in determining what error code to return or whether corrective action can be taken at the driver level. The first patch deals with a ttm_device_init()

[PATCH 13/16] mm: support THP migration to device private memory
Support transparent huge page migration to ZONE_DEVICE private memory. A new flag (MIGRATE_PFN_COMPOUND) is added to the input PFN array to indicate the huge page was fully mapped by the CPU. Export prep_compound_page() so that device drivers can create huge device private pages after calling memremap_pages(). Signed-off-by: Ralph Campbell <rcampbell at nvidia.com> ---
