writeback: add missing requeue_io in writeback_inodes_wb
In "writeback: fix writeback_inodes_wb from writeback_inodes_sb" I accidentally removed the requeue_io if we need to skip a superblock because we can't pin it. Add it back, otherwise we're getting spurious lockups after multiple xfstests runs. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
