Description:
|
||
|
|
This interface allows an admin to set an FC application
|
||
|
|
identifier in the blkcg associated with a cgroup id. The
|
||
|
|
identifier is typically a UUID that is associated with
|
||
|
|
an application or logical entity such as a virtual
|
||
|
|
machine or container group. The application or logical
|
||
|
|
entity utilizes a block device via the cgroup id.
|
||
|
|
FC adapter drivers may query the identifier and tag FC
|
||
|
|
traffic based on the identifier. FC host and FC fabric
|
||
|
|
entities can utilize the application id and FC traffic
|
||
|
|
tag to identify traffic sources.
|
||
|
|
|
||
|
|
The interface expects a string "<cgroupid>:<appid>" where:
|
||
|
|
<cgroupid> is inode of the cgroup in hexadecimal
|
||
|
|
<appid> is user provided string upto 128 characters
|
||
|
|
in length.
|
||
|
|
|
||
|
|
If an appid_store is done for a cgroup id that already
|
||
|
|
has an appid set, the new value will override the
|
||
|
|
previous value.
|
||
|
|
|
||
|
|
If an admin wants to remove an FC application identifier
|
||
|
|
from a cgroup, an appid_store should be done with the
|
||
|
|
following string: "<cgroupid>:"
