[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

A very simple but already quite effective improvement in the handling

[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().
