Qu Wenruo 2c70fe16ea btrfs: remove the nr_ret parameter from __extent_writepage_io() ... The parameter @nr_ret is used to tell the caller how many sectors have been submitted for IO. Then callers check @nr_ret value to determine if we need to manually clear the PAGECACHE_TAG_DIRTY, as if we submitted no sector (e.g. all sectors are beyond i_size) there is no folio_start_writeback() called thus PAGECACHE_TAG_DIRTY tag will not be cleared. Remove this parameter by: - Moving the btrfs_folio_clear_writeback() call into __extent_writepage_io() So that if we didn't submit any IO, then manually call btrfs_folio_set_writeback() to clear PAGECACHE_TAG_DIRTY when the page is no longer dirty. - Use a bool to record if we have submitted any sector Instead of an int. - Use subpage compatible helpers to end folio writeback. This brings no change to the behavior, just for the sake of consistency. As for the call site inside __extent_writepage(), we're always called for the whole page, so the existing full page helper folio_(start|end)_writeback() is totally fine. For the call site inside extent_write_locked_range(), although we can have subpage range, folio_start_writeback() will only clear PAGECACHE_TAG_DIRTY if the page is no longer dirty, and the full folio will still be dirty if there is any subpage dirty range. Only when the last dirty subpage sector is cleared, the folio_start_writeback() will clear PAGECACHE_TAG_DIRTY. So no matter if we call the full page or subpage helper, the result is still the same, then just use the subpage helpers for consistency.
