One of the customer had reported that the set of raid logical arrays will become unavailable (I/O offline) after a long hours of IO stress test. The OS wouldn`t be accessible afterwards and require a hard reset. This driver patch has a fix for race condition between the doorbell and the circular buffer. The driver is modified to do an extra read after clearing the doorbell in case there had been a completion posted during the small timing window. With this fix, we ran IO stress for ~13 days. There were no IO failures. Signed-off-by: Mahesh Rajashekhara <Mahesh.Rajashekhara@pmcs.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com> |
