Added a new sysfs attribute appid_store to set the application identfier in the blkcg associted with cgroup id /sys/class/fc/fc_udev_device/* With this new interface the user can set the application identfier in the blkcg associted with cgroup id. This capability can be utilized by multiple block transport infrastructure like fc,iscsi,roce. Existing FC fabric will use this feature and the description of the use case is below. Various virtualization technologies used in Fibre Channel SAN deployments have created the opportunity to identify and associate traffic with specific virtualized applications. The concepts behind the T11 Application Services standard is to provide the general mechanisms needed to identify virtualized services. It enables the Fabric and the storage targets to identify, monitor, and handle FC traffic based on vm tags by inserting application specific identification into the FC frame. The patches were cut against 5.11/scsi-queue tree v7: Modified the Kconfig comments v6: Addressed the issues reported by kernel test robot Modified the Kconfig files as per standard v5: Renamed the function cgroup_get_from_kernfs_id to cgroup_get_from_id. Moved the input validation at the beginning of the function in Renamed the arguments appropriatley. Changed Return code to non-numeric/SymbolChanged Return code to non-numeric/Symbol Modified the comments. v4: Addressed the error reported by kernel test robot v3: removed RFC. Renamed the functions and app_id to more specific Addressed the reference leaks in blkcg_set_app_identifier Added a new config BLK_CGROUP_FC_APPID and made changes to select the same under SCSI_FC_ATTRS V2: renamed app_identifier to app_id. removed the sysfs interface blkio.app_identifie under /sys/fs/cgroup/blkio Ported the patch on top of 5.10/scsi-queue. Removed redundant code due to changes since last submit. Added a fix for issuing QFPA command.
