There's another
report_cmd.flags = CMD_FLAG_GLOBAL;
above this which gets overwritten here; this command needs to be:
report_cmd.flags = CMD_FLAG_GLOBAL | CMD_FLAG_FOREIGN_OK;
or else
xfs_quota -x -c "report -a"
goes bonkers, iterating in nested loops and printing filesystems multiple times.
It also seems that "report -a" should not be changing defaults this way such
that non-xfs filesystems will get printed; this will be an unexpected change
to default behavior.
Perhaps a top-level "-f" option to explicitly enable foreign filesystem detection
would be best?
