+Description:
+
+Being used for adding and removing rbd block devices.
+
+Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
+
+ $ echo "192.168.0.1 name=admin rbd foo" > /sys/bus/rbd/add
+
+The snapshot name can be "-" or omitted to map the image read/write. A <dev-id>
+will be assigned for any registered block device. If snapshot is used, it will
+be mapped read-only.
+
+Removal of a device:
+
+ $ echo <dev-id> > /sys/bus/rbd/remove
+
+Entries under /sys/bus/rbd/devices/<dev-id>/
+--------------------------------------------
+
+client_id
+
+ The ceph unique client id that was assigned for this specific session.
+
+major
+
+ The block device major number.
+
+name
+
+ The name of the rbd image.
+
+pool
+
+ The pool where this rbd image resides. The pool-name pair is unique
+ per rados system.
+

-Device Interfaces
-
-Introduction
-~~~~~~~~~~~~
-
-Device interfaces are the logical interfaces of device classes that correlate
-directly to userspace interfaces, like device nodes.
-
-Each device class may have multiple interfaces through which you can
-access the same device. An input device may support the mouse interface,
-the 'evdev' interface, and the touchscreen interface. A SCSI disk would
-support the disk interface, the SCSI generic interface, and possibly a raw
-device interface.
-
-Device interfaces are registered with the class they belong to. As devices
-are added to the class, they are added to each interface registered with
-the class. The interface is responsible for determining whether the device
-supports the interface or not.
-
-
-Programming Interface
-~~~~~~~~~~~~~~~~~~~~~
-
-struct device_interface {
- char * name;
- rwlock_t lock;
- u32 devnum;
- struct device_class * devclass;
-
- struct list_head node;
- struct driver_dir_entry dir;
-
- int (*add_device)(struct device *);
- int (*add_device)(struct intf_data *);
-};
-
-int interface_register(struct device_interface *);
-void interface_unregister(struct device_interface *);
-
-
-An interface must specify the device class it belongs to. It is added
-to that class's list of interfaces on registration.
-
-
-Interfaces can be added to a device class at any time. Whenever it is
-added, each device in the class is passed to the interface's
-add_device callback. When an interface is removed, each device is
-removed from the interface.
-
-
-Devices
-~~~~~~~
-Once a device is added to a device class, it is added to each
-interface that is registered with the device class. The class
-is expected to place a class-specific data structure in
-struct device::class_data. The interface can use that (along with
-other fields of struct device) to determine whether or not the driver
-and/or device support that particular interface.
-
-
-Data
-~~~~
-
-struct intf_data {
- struct list_head node;
- struct device_interface * intf;
- struct device * dev;
- u32 intf_num;
-};
-
-int interface_add_data(struct interface_data *);
-
-The interface is responsible for allocating and initializing a struct
-intf_data and calling interface_add_data() to add it to the device's list
-of interfaces it belongs to. This list will be iterated over when the device
-is removed from the class (instead of all possible interfaces for a class).
-This structure should probably be embedded in whatever per-device data
-structure the interface is allocating anyway.
-
-Devices are enumerated within the interface. This happens in interface_add_data()
-and the enumerated value is stored in the struct intf_data for that device.
-
-sysfs
-~~~~~
-Each interface is given a directory in the directory of the device
-class it belongs to:
-
-Interfaces get a directory in the class's directory as well:
-
- class/
- `-- input
- |-- devices
- |-- drivers
- |-- mouse
- `-- evdev
-
-When a device is added to the interface, a symlink is created that points
-to the device's directory in the physical hierarchy:
-
- class/
- `-- input
- |-- devices
- | `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
- |-- drivers
- | `-- usb:usb_mouse -> ../../../bus/drivers/usb_mouse/
- |-- mouse
- | `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
- `-- evdev
- `-- 1 -> ../../../root/pci0/00:1f.0/usb_bus/00:1f.2-1:0/
-
-
-Future Plans
-~~~~~~~~~~~~
-A device interface is correlated directly with a userspace interface
-for a device, specifically a device node. For instance, a SCSI disk
-exposes at least two interfaces to userspace: the standard SCSI disk
-interface and the SCSI generic interface. It might also export a raw
-device interface.
-
-Many interfaces have a major number associated with them and each
-device gets a minor number. Or, multiple interfaces might share one
-major number, and each will receive a range of minor numbers (like in
-the case of input devices).
-
-These major and minor numbers could be stored in the interface
-structure. Major and minor allocations could happen when the interface
-is registered with the class, or via a helper function.
-
The representation of the above is reflected in the directory tree
in EDAC's sysfs interface. Starting in directory
/sys/devices/system/edac/mc each memory controller will be represented
-by its own 'mcX' directory, where 'X" is the index of the MC.
+by its own 'mcX' directory, where 'X' is the index of the MC.
..../edac/mc/
....
Under each 'mcX' directory each 'csrowX' is again represented by a
-'csrowX', where 'X" is the csrow index:
+'csrowX', where 'X' is the csrow index:
.../mc/mc0/
In 'mcX' directories are EDAC control and attribute files for
-this 'X" instance of the memory controllers:
+this 'X' instance of the memory controllers:
Counter reset control file:
'csrowX' DIRECTORIES
In the 'csrowX' directories are EDAC control and attribute files for
-this 'X" instance of csrow:

Total Uncorrectable Errors count attribute file:
releasepage: releasepage is called on PagePrivate pages to indicate
that the page should be freed if possible. ->releasepage
should remove any private data from the page and clear the
- PagePrivate flag. It may also remove the page from the
- address_space. If this fails for some reason, it may indicate
- failure with a 0 return value.
- This is used in two distinct though related cases. The first
- is when the VM finds a clean page with no active users and
+ PagePrivate flag. If releasepage() fails for some reason, it must
+ indicate failure with a 0 return value.
+ releasepage() is used in two distinct though related cases. The
+ first is when the VM finds a clean page with no active users and
wants to make it a free page. If ->releasepage succeeds, the
page will be removed from the address_space and become free.
Count buffering overhead as bytes/2^tcp_adv_win_scale
(if tcp_adv_win_scale > 0) or bytes-bytes/2^(-tcp_adv_win_scale),
if it is <= 0.
+ Possible values are [-31, 31], inclusive.

- Instructions for use
- --------------------
+ For usage instructions, please refer to:
- 1) Map a Linux block device to an existing rbd image.
-
- Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
-
- $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
-
- The snapshot name can be "-" or omitted to map the image read/write.
-
- 2) List all active blkdev<->object mappings.
-
- In this example, we have performed step #1 twice, creating two blkdevs,
- mapped to two separate rados objects in the rados rbd pool
-
- $ cat /sys/class/rbd/list
- #id major client_name pool name snap KB
- 0 254 client4143 rbd foo - 1024000
-
- The columns, in order, are:
- - blkdev unique id
- - blkdev assigned major
- - rados client id
- - rados pool name
- - rados block device name
- - mapped snapshot ("-" if none)
- - device size in KB
-
-
- 3) Create a snapshot.
-
- Usage: <blkdev id> <snapname>
-
- $ echo "0 mysnap" > /sys/class/rbd/snap_create
-
-
- 4) Listing a snapshot.
-
- $ cat /sys/class/rbd/snaps_list
- #id snap KB
- 0 - 1024000 (*)
- 0 foo 1024000
-
- The columns, in order, are:
- - blkdev unique id
- - snapshot name, '-' means none (active read/write version)
- - size of device at time of snapshot
- - the (*) indicates this is the active version
-
- 5) Rollback to snapshot.
-
- Usage: <blkdev id> <snapname>
-
- $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
-
-
- 6) Mapping an image using snapshot.
-
- A snapshot mapping is read-only. This is being done by passing
- snap=<snapname> to the options when adding a device.
-
- $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
-
-
- 7) Remove an active blkdev<->rbd image mapping.
-
- In this example, we remove the mapping with blkdev unique id 1.
-
- $ echo 1 > /sys/class/rbd/remove
-
-
- NOTE: The actual creation and deletion of rados objects is outside the scope
- of this driver.
