exfat: fix setting uninitialized time to ctime/atime

2023-11-03T13:24:07Z

An uninitialized time is set to ctime/atime in __exfat_write_inode(). It causes xfstests generic/003 and generic/192 to fail. And since there will be a time gap between setting ctime/atime to the inode and writing back the inode, so ctime/atime should not be set again when writing back the inode.

exfat: add ioctls for accessing attributes

2023-10-31T01:00:51Z

Add GET and SET attributes ioctls to enable attribute modification. We already do this in FAT and a few userspace utils made for it would benefit from this also working on exFAT, namely fatattr. Signed-off-by: Jan Cincera Signed-off-by: Namjae Jeon

exfat: convert to ctime accessor functions

In later patches, we're going to change how the inode's ctime field is used. Switch to using accessor functions instead of raw accesses of inode->i_ctime. Signed-off-by: Jeff Layton Reviewed-by: Jan Kara Message-Id: <20230705190309.579783-38-jlayton@kernel.org> Signed-off-by: Christian Brauner

extfat: remove ->writepage

2022-12-12T02:12:17Z

Patch series "start removing writepage instances v2". The VM doesn't need or want ->writepage for writeback and is fine with just having ->writepages as long as ->migrate_folio is implemented. This series removes all ->writepage instances that use block_write_full_page directly and also have a plain mpage_writepages based ->writepages. This patch (of 7): ->writepage is a very inefficient method to write back data, and only used through write_cache_pages or a a fallback when no ->migrate_folio method is present. Set ->migrate_folio to the generic buffer_head based helper, and remove the ->writepage implementation.

exfat: remove i_size_write() from __exfat_truncate()

2022-12-12T02:02:51Z

The file/directory size is updated into inode by i_size_write() before __exfat_truncate() is called, so it is redundant to re-update by i_size_write() in __exfat_truncate().
