cramfs: fix incorrect physical page address calculation

2025-09-28T18:36:12+00:00

Commit 21aa65bf82a7 ("mm: remove callers of pfn_t functionality") incorrectly replaced the pfn with the physical address when calling vmf_insert_mixed(). Instead the phys_to_pfn_t() call should have been replaced with PHYS_PFN(). Found by inspection after a similar issue was noted in fuse virtio_fs.

mm: remove callers of pfn_t functionality

2025-07-10T05:42:19+00:00

All PFN_* pfn_t flags have been removed. Therefore there is no longer a need for the pfn_t type and all uses can be replaced with normal pfns.

mm: remove remaining uses of PFN_DEV

2025-07-10T05:42:16+00:00

PFN_DEV was used by callers of dax_direct_access() to figure out if the returned PFN is associated with a page using pfn_t_has_page() or not. However all DAX PFNs now require an assoicated ZONE_DEVICE page so can assume a page exists. Other users of PFN_DEV were setting it before calling vmf_insert_mixed(). This is unnecessary as it is no longer checked, instead relying on pfn_valid() to determine if there is an associated page or not.

cramfs: Convert cramfs_read_folio to use a folio

2024-05-31T10:31:39+00:00

Remove the conversion back into a page and use the folio APIs throughout. Remove the setting of PG_error instead of converting it; it is unused by core code or by the rest of cramfs, so it serves no purpose here. Use folio_end_read() to save an atomic operation and unify the two exit paths.

fs,block: yield devices early

2024-03-27T12:17:15+00:00

Currently a device is only really released once the umount returns to userspace due to how file closing works. That ultimately could cause an old umount assumption to be violated that concurrent umount and mount don't fail. So an exclusively held device with a temporary holder should be yielded before the filesystem is gone. Add a helper that allows callers to do that. This also allows us to remove the two holder ops that Linus wasn't excited about.
