driver removal problems with mptsas?
Hello,
I have noticed that if I 'rmmod mptsas', the scsi_eh_<n> kernel thread is not stopped. If I 'modprobe mptsas' a new scsi_eh_<n> is started. If I put the above in a loop, a new scsi_eh_<n> is started for each modprobe of mptsas.
I also believe that mptsas is not cleaning up properly when removed. I have a 1068 and during probe, sas_phy_alloc() is called for each of the 8 phys. During mptsas_remove() I would expect to see those 8 allocated sas_phy structures freed by calls to sas_phy_delete()/sas_phy_free(). Or are they removed elsewhere?
I'm running 2.6.16.18 and using LSISAS1068 card.

Hi Scott,
Your right this was a problem, but was addressed with a recent patch in scsi-misc:
