    Subject[PATCH 0/7] writeback: avoid touching dirtied_when on blocked inodes

    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
