*	xfs: add log attributes for log lsn and grant head data	Brian Foster	2014-07-15	1	-0/+64
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Create log attributes to export the current runtime state of the log to sysfs. Note that the filesystem should be frozen for consistency across attributes. The following per-mount attributes are created: log_head_lsn, log_tail_lsn, reserve_grant_head and write_grant_head. These represent the physical log head, tail and reserve and write grant heads respectively. Attribute values are exported in the following format: "cycle:[block,byte]" ... where cycle represents the log cycle and [block,bytes] represents either the basic block or byte offset of the log, depending on the attribute. Log sequence number (LSN) values are encoded in basic blocks and grant heads are encoded in bytes. All values are in decimal format.

*	xfs: add xlog sysfs kobject and attribute handlers	Brian Foster	2014-07-15	1	-0/+52
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Embed a kobject into the xfs log data structure (xlog). This creates a 'log' subdirectory for every XFS mount instance in sysfs. The lifecycle of the log kobject is tied to the lifecycle of the log. Also define a set of generic attribute handlers associated with the log kobject in preparation for the addition of attributes.

*	xfs: add xfs_mount sysfs kobject	Brian Foster	2014-07-15	1	-0/+49
	Embed a base kobject into xfs_mount. This creates a kobject associated with each XFS mount and a subdirectory in sysfs with the name of the filesystem. The subdirectory lifecycle matches that of the mount. Also add the new xfs_sysfs.[c,h] source files with some XFS sysfs infrastructure to facilitate attribute creation. Note that there are currently no attributes exported as part of the xfs_mount kobject. It exists solely to serve as a per-mount container for child objects.
