Hi,

在 2023/12/12 21:16, Christoph Hellwig 写道:
+void invalidate_bdev_range(struct block_device *bdev, pgoff_t start,
+ pgoff_t end)
+{
+ invalidate_mapping_pages(bdev->bd_inode->i_mapping, start, end);
+}
+EXPORT_SYMBOL_GPL(invalidate_bdev_range);

Can we have kerneldoc comments for the new helpers please?

Of course, will definitely do this in v3.

+struct folio *__bdev_get_folio(struct block_device *bdev, loff_t pos,
+ fgf_t fgp_flags, gfp_t gfp)
+{
+ return __filemap_get_folio(bdev->bd_inode->i_mapping, pos >> PAGE_SHIFT,
+ fgp_flags, gfp);
+}
+EXPORT_SYMBOL_GPL(__bdev_get_folio);

It's a bit silly to have a __-prefixed API without a version that
doesn't have the prefix, so I'd prefer to drop it. Unless willy has
a good argument for keeping it the same as the filemap API.

Ok, I'll drop it if willy doesn't against this.

Thanks,
Kuai
