| 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>:"
