Hi, Tejun,

We often see this warning when using sata disks with libsas:

[26705.760518] WARNING: CPU: 1 PID: 6796 at drivers/ata/libata-eh.c:4037 
ata_eh_finish+0xb4/0xcc

This seems implies that ap->nr_active_links is wrong and should be zero.
But I didn't see any other errors. The disks work well.

Question:
ap->nr_active_links seems can be modified by different cpus 
simultaneously, should it be atomic_t? Is this the reason of the warning
above?

Which kernel version are you running on what sort of device?  Can you
post the full log?

Thanks.

We have tested kernel 4.12 to 4.15, all have this warning.
Some sas/sata disks directly connected to hisi sas controller.

The full log is as follows, please ignore the duplicated log because I 
didn't close the boot console.
