Hi,
I see following two ways to add sub-directories under the /sys/class/
fc_host/hostX/ in sysfs.
a) Add a new attribute_group for each directory to be created in
transport_container structure.
2) Create a sysfs group and add attributes to it in the transport
layer.
I was thinking of second approach, since the sub-directories that
needs to be added, may not be a generic one and specific to transport.
In such a case adding the attribute group to transport_container
structure may affect all other transport layer. Keeping it local to
particular transport layer will restrict the changes to a particular
transport layer.
I see class devices getting added to the system after host setup
routine is completed by transport layer. These sub-directories needs
to be created after the class devices are added to the system. Hence,
I was thinking of doing this in FC transport layer by passing
host_configure routine as part of transport class declaration.
During, host configure routine, the transport layer will go ahead and
create the sub-directories and add the attributes to them.
Thanks,
Giridhar.M.B
