dm bufio: fix error code in dm_bufio_write_dirty_buffers()
We should be returning normal negative error codes here. The "a" variables comes from &c->async_write_error which is a blk_status_t converted to a regular error code. In the current code, the blk_status_t gets propogated back to pool_create() and eventually results in an Oops. Fixes: 4e4cbee93d56 ("block: switch bios to blk_status_t") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
