fat: report creation time in statx

2022-05-19T21:10:31+00:00

creation time is no longer mixed with change time. Add an in-memory field for it, and report it in statx if supported. Link: https://lkml.kernel.org/r/20220503152536.2503003-3-cccheng@synology.com Signed-off-by: Chung-Chiang Cheng Acked-by: OGAWA Hirofumi Signed-off-by: Andrew Morton

fat: ignore ctime updates, and keep ctime identical to mtime in memory

2022-05-19T21:10:31+00:00

FAT supports creation time but not change time, and there was no corresponding timestamp for creation time in previous VFS. The original implementation took the compromise of saving the in-memory change time into the on-disk creation time field, but this would lead to compatibility issues with non-linux systems. To address this issue, this patch changes the behavior of ctime. It will no longer be loaded and stored from the creation time on disk. Instead of that, it'll be consistent with the in-memory mtime and share the same on-disk field. All updates to mtime will also be applied to ctime in memory, while all updates to ctime will be ignored.

fs: Convert mpage_readpage to mpage_read_folio

2022-05-09T20:21:44+00:00

mpage_readpage still works in terms of pages, and has not been audited for correctness with large folios, so include an assertion that the filesystem is not passing it large folios. Convert all the filesystems to call mpage_read_folio() instead of mpage_readpage(). Signed-off-by: Matthew Wilcox (Oracle)

block: remove QUEUE_FLAG_DISCARD

2022-04-18T01:49:59+00:00

Just use a non-zero max_discard_sectors as an indicator for discard support, similar to what is done for write zeroes. The only places where needs special attention is the RAID5 driver, which must clear discard support for security reasons by default, even if the default stacking rules would allow for it.

Pull filesystem folio updates from Matthew Wilcox: "Primarily this series converts some of the address_space operations to take a folio instead of a page. Notably: - a_ops->is_partially_uptodate() takes a folio instead of a page and changes the type of the 'from' and 'count' arguments to make it obvious they're bytes. - a_ops->invalidatepage() becomes ->invalidate_folio() and has a similar type change. - a_ops->launder_page() becomes ->launder_folio() - a_ops->set_page_dirty() becomes ->dirty_folio() and adds the address_space as an argument.
