2022-01-12Merge tag 'libnvdimm-for-5.17' of ↵Linus Torvalds6-62/+13
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull dax and libnvdimm updates from Dan Williams: "The bulk of this is a rework of the dax_operations API after discovering the obstacles it posed to the work-in-progress DAX+reflink support for XFS and other copy-on-write filesystem mechanics. Primarily the need to plumb a block_device through the API to handle partition offsets was a sticking point and Christoph untangled that dependency in addition to other cleanups to make landing the DAX+reflink support easier. The DAX_PMEM_COMPAT option has been around for 4 years and not only are distributions shipping userspace that understand the current configuration API, but some are not even bothering to turn this option on anymore, so it seems a good time to remove it per the deprecation schedule. Recall that this was added after the device-dax subsystem moved from /sys/class/dax to /sys/bus/dax for its sysfs organization. All recent functionality depends on /sys/bus/dax. Some other miscellaneous cleanups and reflink prep patches are included as well. Summary: - Simplify the dax_operations API: - Eliminate bdev_dax_pgoff() in favor of the filesystem maintaining and applying a partition offset to all its DAX iomap operations. - Remove wrappers and device-mapper stacked callbacks for ->copy_from_iter() and ->copy_to_iter() in favor of moving block_device relative offset responsibility to the dax_direct_access() caller. - Remove the need for an @bdev in filesystem-DAX infrastructure - Remove unused uio helpers copy_from_iter_flushcache() and copy_mc_to_iter() as only the non-check_copy_size() versions are used for DAX. - Prepare XFS for the pending (next merge window) DAX+reflink support - Remove deprecated DEV_DAX_PMEM_COMPAT support - Cleanup a straggling misuse of the GUID api" * tag 'libnvdimm-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (38 commits) iomap: Fix error handling in iomap_zero_iter() ACPI: NFIT: Import GUID before use dax: remove the copy_from_iter and copy_to_iter methods dax: remove the DAXDEV_F_SYNC flag dax: simplify dax_synchronous and set_dax_synchronous uio: remove copy_from_iter_flushcache() and copy_mc_to_iter() iomap: turn the byte variable in iomap_zero_iter into a ssize_t memremap: remove support for external pgmap refcounts fsdax: don't require CONFIG_BLOCK iomap: build the block based code conditionally dax: fix up some of the block device related ifdefs fsdax: shift partition offset handling into the file systems dax: return the partition offset from fs_dax_get_by_bdev iomap: add a IOMAP_DAX flag xfs: pass the mapping flags to xfs_bmbt_to_iomap xfs: use xfs_direct_write_iomap_ops for DAX zeroing xfs: move dax device handling into xfs_{alloc,free}_buftarg ext4: cleanup the dax handling in ext4_fill_super ext2: cleanup the dax handling in ext2_fill_super fsdax: decouple zeroing from the iomap buffered I/O code ...

2022-01-12perf cpumap: Give CPUs their own typeIan Rogers64-356/+431
A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t.
