This Patch added a unique application identifier i.e
app_id knob to blkcg which allows identification of traffic
sources at an individual cgroup based Applications
(ex:virtual machine (VM))level in both host and
fabric infrastructure.
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
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.

Added a new function cgroup_get_from_id to retrieve the cgroup
associated with cgroup id.
Exported the same as this can be used by blk-cgorup.c
Added function declaration of cgroup_get_from_id in cgorup.h
This patch also exported the function cgroup_get_e_css
as this is getting used in blk-cgroup.h

Added a new sysfs attribute appid_store under
/sys/class/fc/fc_udev_device/*
With this new interface the user can set the application identfier
in the blkcg associted with cgroup id.
Once the application identifer has set with this interface it allows
identification of traffic sources at an individual cgroup based
Applications (ex:virtual machine (VM))level in both host and
fabric infrastructure(FC).
Below is the interface provided to set the app_id
echo "<cgroupid>:<appid>" >> /sys/class/fc/fc_udev_device/appid_store

[-- Attachment #1: Type: text/plain, Size: 10381 bytes --]
From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>
This patch adds additional data structures for supporting the
two versions of vmid implementation. First type uses app header
while the other types uses priority tagging mechanism.
These data structures are used mostly for ELS and
CT commands for the two vmid implementation.
The API determines if VMID is enabled by the user or not.

From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>
This patch does the following -
1.adds supporting datastructures for mailbox command which helps in
determining if the firmware supports appid or not.
2.This patch allocates the resource for vmid and checks if the firmware
supports the feature or not.
3.The patch cleans up the vmid resources and stops the timer.

From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>
This patch contains the routines to save, retrieve and remove the vmids
from the data structure. A hash table is used to save the vmids and
the corresponding UUIDs associated with the application/VMs.

From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>
The patch implements CT commands for registering and deregistering the
appid for the application. Also, a small change in decrementing the ndlp
ref counter has been added.

The patch introduces the vmid in the io path. It checks if the vmid is
enabled and if io belongs to a vm or not and acts accordingly. Other
supporing APIs are also included in the patch.

Please follow coding-style for Kconfig files:
from Documentation/process/coding-style.rst, section 10):
For all of the Kconfig* configuration files throughout the source tree,
the indentation is somewhat different. Lines under a ``config`` definition
are indented with one tab, while help text is indented an additional two
spaces.
thanks.

Please follow coding-style for Kconfig files:
from Documentation/process/coding-style.rst, section 10):
For all of the Kconfig* configuration files throughout the source tree,
the indentation is somewhat different. Lines under a ``config``
definition are indented with one tab, while help text is indented an
additional two spaces.
thanks.
