// Package xfs provides access to statistics exposed by the XFS filesystem.

// The names and meanings of each statistic were taken from
// http://xfs.org/index.php/Runtime_Stats and xfs_stats.h in the Linux
// kernel source. Most counters are uint32s (same data types used in
// xfs_stats.h), but some of the "extended precision stats" are uint64s.

// If empty, this indicates aggregated statistics for all XFS
