[PATCHv2]sd: Don't treat succeeded SYNC as error

Hi, all We hit IO error on fsync, it turns out was because sd treat succeeded SYNC as error. From what I checked in SBC spec there is no indication we should fail IO in this case, so we create this patch. Best Regards, Jack Wang v2: No change on patch itself, only resend in body as suggested b

Hello Bart Around 300s before the paths were declared hard failed and the devices offlined. This is when I/O restarts. The remaining paths on the second Qlogic port (that are not jammed) will not be used until the error handler activity completes. Until we get these for example, and device-mappe

[PATCH v2 00/12] scsi_debug: multiple queue support and cleanup

[PATCH v2 03/12] scsi_debug: replace jiffy timers with hr timers

The driver supports two command delay interfaces, the original one whose unit is a jiffy, and a newer one whose unit is a nanosecond. Each had different implementations. Keep both interfaces but simplify the implemenation to use a single delay mechanism based on high resolution timers. Signed-off-

[PATCH v2 05/12] scsi_debug: replace tasklet with work queue

When a negative value was placed in the delay parameter, a tasklet was scheduled. Change the tasklet to a work queue. Previously a delay of -1 scheduled a high priority tasklet; since there are no high priority work queues, treat -1 like other negative values in delay and schedule a work item. Sig

[PATCH v2 02/12] scsi_debug: ignore host lock option

Remove logic to optionally hold host_lock while each command is queued. Keep module and sysfs host_lock parameters for backward compatibility. Note in module parameter description that host_lock is ignored. Signed-off-by: Douglas Gilbert --- drivers/scsi/scsi_debug.c | 44 +++
