Hi,
This tries to keep dirtied_when for blocked inodes by converting some
redirty_tail() calls to requeue_io_wait(). The possibly blocked inodes
will be moved to b_more_io_wait. The b_more_io_wait inodes will now be
retried as dillegent as b_more_io inodes, except when the latter goes empty,
b_more_io_wait will be retried by the kupdate work on increasing intervals
until exceeding dirty_writeback_interval.

writeback: avoid redirtying when ->write_inode failed to clear I_DIRTY
Jan Kara (2):
writeback: update wb->last_active on written pages/inodes
writeback: Retry kupdate work early if we need to retry some inode writeback
Wu Fengguang (4):
writeback: introduce queue b_more_io_wait
writeback: requeue_io_wait() on pages_skipped inode
writeback: requeue_io_wait() on blocked inode
writeback: requeue_io_wait() when failed to grab superblock
