[PATCH v5 08/11] wait_bit: introduce {wait_on,wake_up}_atomic_one

Add a generic facility for awaiting an atomic_t to reach a value of 1. Page reference counts typically need to reach 0 to be considered a free / inactive page. However, ZONE_DEVICE pages allocated via devm_memremap_pages() are never 'onlined', i.e. the put_page() typically done at init time to

It is possible to indirectly invoke functions with prototypes that do not match those of the respectively used function pointers by using void types. Despite widely used as a feature for relaxing function invocation, this should be avoided when possible as it may prevent the use of heuristics such

[PATCH v5 06/11] mm, dax: enable filesystems to trigger dev_pagemap ->page_free callbacks

In order to resolve collisions between filesystem operations and DMA to DAX mapped pages we need a callback when DMA completes. With a callback we can hold off filesystem operations while DMA is in-flight and then resume those operations when the last put_page() occurs on a DMA page. Recall that

[PATCH v5 09/11] mm, fs, dax: handle layout changes to pinned dax mappings

Background: get_user_pages() in the filesystem pins file backed memory pages for access by devices performing dma. However, it only pins the memory pages not the page-to-file offset association. If a file is truncated the pages are mapped out of the file and dma may continue indefinitely into a

[PATCH v5 07/11] mm, dev_pagemap: introduce CONFIG_DEV_PAGEMAP_OPS

The HMM sub-system extended dev_pagemap to arrange a callback when a dev_pagemap managed page is freed. Since a dev_pagemap page is free / idle when its reference count is 1 it requires an additional branch to check the page-type at put_page() time. Given put_page() is a hot-path we do not want to

[PATCH v5 05/11] fs, dax: use page->mapping to warn if truncate collides with a busy page

Catch cases where extent unmap operations encounter pages that are pinned / busy. Typically this is pinned pages that are under active dma. This warning is a canary for potential data corruption as truncated blocks could be allocated to a new file while the device is still performing i/o. Here is

[PATCH v5 11/11] xfs, dax: introduce xfs_break_dax_layouts()

xfs_break_dax_layouts(), similar to xfs_break_leased_layouts(), scans for busy / pinned dax pages and waits for those pages to go idle before any potential extent unmap operation. dax_layout_busy_page() handles synchronizing against new page-busy events (get_user_pages). It invalidates all

[PATCH v5 10/11] xfs: prepare xfs_break_layouts() for another layout type

When xfs is operating as the back-end of a pNFS block server, it prevents collisions between local and remote operations by requiring a lease to be held for remotely accessed blocks. Local filesystem operations break those leases before writing or mutating the extent map of the file. A similar
