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>:"
