Subject: turn hmm migrate_vma upside down v3
Date: Wed, 14 Aug 2019 09:59:18 +0200 [thread overview]
Message-ID: <20190814075928.23766-1-hch@lst.de> (raw)
Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which starts revamping the
migrate_vma functionality. The prime idea is to export three slightly
lower level functions and thus avoid the need for migrate_vma_ops
callbacks.

- minor style fixes
- add a new patch to remove CONFIG_MIGRATE_VMA_HELPER
Changes since v1:
- fix a few whitespace issues
- drop the patch to remove MIGRATE_PFN_WRITE for now
- various spelling fixes
- clear cpages and npages in migrate_vma_setup
- fix the nouveau_dmem_fault_copy_one return value
- minor improvements to some nouveau internal calling conventions
