Hello, this patch series fixes an issue with handling of lazy inode timestamp writeback which could result in missed background writeback of an inode or missed update of inode timestamps during sync(2). It also somewhat simplifies the writeback code handling of lazy inode timestamp updates. Changes since v1: * Split off locking change for i_io_list manipulation to a separate patch * Renamed older_than_this to dirtied_before * Renamed __redirty_tail() to redirty_tail_locked() * Other minor style fixes Honza Previous versions: Link: http://lore.kernel.org/r/20200601091202.31302-1-jack@xxxxxxx
