That's no surprise - there are still some formats of inodes that we
cannot exchange because the code in xfs_fsr cannot precisely control
the format of the inode forks from userspace. If you use the event
tracing to capture the before and after swap extent trace points, I
can tell you why they were incompatible for exchange, and whether
xfs_fsr can be further modified to enable those files to be
defragmented....

Cheers,

Dave.
