    xfs: add log attributes for log lsn and grant head data
    
    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
    
    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
    
    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.

    xfs: add a sysfs kset
    
    Create a sysfs kset to contain all sub-objects associated with the XFS
    module. The kset is created and removed on module initialization and
    removal respectively. The kset uses fs_obj as a parent. This leads to
    the creation of a /sys/fs/xfs directory when the kset exists.

    xfs: fix a couple error sequence jumps in xfs_mountfs()
    
    xfs_mountfs() has a couple failure conditions that do not jump to the
    correct labels. Specifically:
    
    - xfs_initialize_perag_data() failure does not deallocate the log even
      though it occurs after log initialization
    - xfs_mount_reset_sbqflags() failure returns the error directly rather
      than jump to the error sequence
