Linus Torvalds 7a7fd0de4a Merge branch 'kmap-conversion-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux ... Pull kmap conversion updates from David Sterba: "This contains changes regarding kmap API use and eg conversion from kmap_atomic to kmap_local_page. The API belongs to memory management but to save cross-tree dependency headaches we've agreed to take it through the btrfs tree because there are some trivial conversions possible, while the rest will need some time and getting the easy cases out of the way would be convenient. The changes can be grouped: - function exports, new helpers - new VM_BUG_ON for additional verification; it's been discussed if it should be VM_BUG_ON or BUG_ON, the former was chosen due to performance reasons - code replaced by relevant helpers" [ This is an updated version of a request that originally came in during the merge window, but I asked for some updates: https://lore.kernel.org/lkml/cover.1614090658.git.dsterba@suse.com/ which is why this got merge after the merge window closed. - Linus ] * 'kmap-conversion-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: use copy_highpage() instead of 2 kmaps() btrfs: use memcpy_[to|from]_page() and kmap_local_page() mm/highmem: Add VM_BUG_ON() to mem*_page() calls mm/highmem: Introduce memcpy_page(), memmove_page(), and memset_page() mm/highmem: Convert memcpy_[to|from]_page() to kmap_local_page() mm/highmem: Lift memcpy_[to|from]_page to core		2021-03-01 11:24:18 -08:00
