For the moment it uses the same data structures, enabling a gradual replacement. This patch set implements the XArray and converts the page cache to use it. A version of these patches has been running under xfstests for over 48 hours, so I have some confidence in them. The DAX changes are untested. This is based on next-20180608 and is available as a git tree at git://git.infradead.org/users/willy/linux-dax.git xarray-20180608 My plan for getting this lot merged is to create a git branch from -rc1 and ask that to be included in -next. Last call for reviews/acks. I'd suggest looking at the page cache changes (patches 19-68) rather than the XArray patches themselves. I know there's a lot of patches, but each individual patch is quite small. In particular, I'd like reviews from filesystem people of their own filesystem conversions. I have that from David Sterba for btrfs, but I've had no response from the nilfs2 or f2fs people. Changes since v12: - Fixed bug in page cache lookup conversion which could lead to returning pages which had been released from the page cache. Split out the seven converted functions each into their own patch to allow for better bisection. - Fixed bug in workingset conversion that led to exceptional entries not being deleted from the XArray. - Fixed several bugs in DAX conversion. - Added xas_for_each_conflict() and use it in DAX. - Undid change of xas_load() behaviour with multislot xa_state that was introduced in v10. Removed test cases, since we don't want that behaviour. - Re-added conversion of dax_layout_busy_page. - Reordered a DAX bugfix to the head of the queue to allow it to be merged independently. - Dropped "dax_insert_mapping_entry always succeeds" due to being merged by Dan. Thanks, Dan! - Dropped "dax: Return fault code from dax_load_hole" as it was taken care of by Souptick's patch. - At Ross's request, renamed dax_mk_foo() to dax_make_foo(). - Renamed DAX_ENTRY_LOCK to DAX_LOCKED. - Updated migrate_page_move_mapping conversion. - Split out the radix tree test suite addition of ubsan. - Split out radix tree code deletion. - Removed __radix_tree_create from the public API. - Fixed up a couple of comments in DAX. - Renamed shmem_xa_replace() to shmem_replace_entry(). - Corrected some typos in the XArray kerneldoc and reworded a few sentences in xarray.rst. - Added a new section on multi-index entries to xarray.rst, replacing the single paragraph we used to have. - Fixed multi-index xas_store(xas, NULL) and added test-cases. - Fixed multi-index xas_store() in the presence of tags (the new entry is tagged if any of the entries it is replacing is tagged). - Dropped lustre patch due to removal from staging - Use XA_BUG_ON() more in the test suite rather than assert(). Conversion not completed. - Deleted an unused variable from nilfs2 conversion. - Rename f2fs_clear_radix_tree_dirty_tag to f2fs_clear_page_cache_dirty_tag Matthew Wilcox (72): radix tree test suite: Enable ubsan dax: Fix use of zero page xarray: Replace exceptional entries xarray: Change definition of sibling entries xarray: Add definition of struct xarray xarray: Define struct xa_node xarray: Add documentation xarray: Add xa_load xarray: Add XArray tags xarray: Add xa_store xarray: Add xa_cmpxchg and xa_insert xarray: Add xa_for_each xarray: Add xa_extract xarray: Add xa_destroy xarray: Add xas_next and xas_prev xarray: Add xas_for_each_conflict xarray: Add xas_create_range xarray: Add MAINTAINERS entry page cache: Rearrange address_space page cache: Convert hole search to XArray page cache: Add and replace pages using the XArray page cache: Convert page deletion to XArray page cache: Convert find_get_entry to XArray page cache: Convert find_get_entries to XArray page cache: Convert find_get_pages_range to XArray page cache: Convert find_get_pages_contig to XArray page cache;
