    xfs: remove the global xfs_Gqm structure
    
    If we initialize the slab caches for the quota code when XFS is loaded there
    is no need for a global and reference counted quota manager structure.  Drop
    all this overhead and also fix the error handling during quota initialization.

    xfs: remove the per-filesystem list of dquots
    
    Instead of keeping a separate per-filesystem list of dquots we can walk
    the radix tree for the two places where we need to iterate all quota
    structures.

    xfs: use per-filesystem radix trees for dquot lookup
    
    Replace the global hash tables for looking up in-memory dquot structures
    with per-filesystem radix trees to allow scaling to a large number of
    in-memory dquot structures.

commit f8739c3ce2ac9a01515b56026b6a066c0808234b
Author: Christoph Hellwig <hch at infradead.org>
Date:   Tue Mar 13 08:52:34 2012 +0000

    xfs: per-filesystem dquot LRU lists
    
    Replace the global dquot lru lists with a per-filesystem one.
    
    Note that the shrinker isn't wire up to the per-superblock VFS shrinker
    infrastructure as would have problems summing up and splitting the counts
    for inodes and dquots.  I don't think this is a major problem as the quota
    cache isn't as interwinded with the inode cache as the dentry cache is,
    because an inode that is dropped from the cache will generally release
    a dquot reference, but most of the time it won't be the last one.

    xfs: use common code for quota statistics
    
    Switch the quota code over to use the generic XFS statistics infrastructure.
    While the legacy /proc/fs/xfs/xqm and /proc/fs/xfs/xqmstats interfaces are
    preserved for now the statistics that still have a meaning with the current
    code are now also available from /proc/fs/xfs/stats.
