Bug Description
From the patch series cover letter:
Now the libsas hotplug has some issues, Dan Williams report
a similar bug here before
https://<email address hidden>
The issues we have found
1. if LLDD burst reports lots of phy-up/phy-down sas events, some events
may lost because a same sas events is pending now, finally libsas topo
may different the hardware.
2. receive a phy down sas event, libsas call sas_deform_port to remove
devices, it would first delete the sas port, then put a destruction
discovery event in a new work, and queue it at the tail of workqueue,
once the sas port be deleted, its children device will be deleted too,
when the destruction work start, it will found the target device has
been removed, and report a sysfs warnning.
3. since a hotplug process will be devided into several works, if a phy up
sas event insert into phydown works, like
destruction work ---> PORTE_BYTES_DMAED (sas_form_port) ---->PHYE_
the hot remove flow would broken by PORTE_BYTES_DMAED event, it's not
we expected, and issues would occur.
There's also a small 3-patch series of fixes in libsas I plan to include as well:
Jason Yan (2):
scsi: libsas: fix memory leak in sas_smp_
scsi: libsas: fix error when getting phy events
chenxiang (1):
scsi: libsas: initialize sas_phy status according to response of
