OK, will make it atomic in next version, thanks for the advice.
Perhaps I can add two scsi helper functions in scsi_lib.c like:
void sdev_disable_disk_events(struct scsi_device *sdev)
{
atomic_inc(&sdev->disk_events_disable_depth);
}
void sdev_enable_disk_events(struct scsi_device *sdev)
{
if (WARN_ON_ONCE(atomic_read(&sdev->disk_events_disable_depth) <= 0))
return;
atomic_dec(&sdev->disk_events_disable_depth);
}
And call them in ATA layer. Do you like this?
Sounds good to me. James, how does the series look to you?
Indeed. Want James' Acked-by for patch #1.
I think it's ready. It can go into libata-dev.git #upstream, and be
reverted prior to Linus push if James NAKs.
