From: Tom Jackson <redacted> Per the SAS spec, several types of BROADCAST CHANGE primitives must cause re-discovery of the originating expander. Only the standard BROADCAST CHANGE primitive was being sent to the LIBSAS layer. The other BC primitives have been added to the sci_phy_event_handler() Signed-off-by: Tom Jackson <redacted> Signed-off-by: Dan Williams <redacted> --- drivers/scsi/isci/phy.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-)
