203 	 * async write failure retry count. Initialised to zero on the first
208 	 * For retry timeouts, we record the jiffy of the first failure. This
209 	 * means that we can change the retry timeout for buffers already under
210 	 * I/O and thus avoid getting stuck in a retry loop with a long timeout.
212 	 * last_error is used to ensure that we are getting repeated errors, not

214 	 * a failure timeout occurs, so we want to re-initialise the error
215 	 * retry behaviour appropriately when that happens.
