my xfs_fsr version is xfsdump_2.2.48-1,

there is a description in xfs_fsr man said
When invoked with no arguments xfs_fsr reorganizes all regular files in 
all mounted filesystems.
Each pass goes through and selects files that have the largest number of 
extents.  It attempts to defragment the top 10% of these files on each pass.
but xfs_fsr -d telling me it defrags in inode ascending order,


is this a normal behavior?
