Hello.

I found following problem with xfs_info (xfs_grows -p xfs_info) command:

# mkfs.xfs -f /dev/loop0     
meta-data=/dev/loop0             isize=256    agcount=4, agsize=32000 blks
         =                       sectsz=512   attr=2
data     =                       bsize=4096   blocks=128000, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096  
log      =internal log           bsize=4096   blocks=1200, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
# mount /dev/loop0 /mnt/usb
# xfs_info /mnt/usb
meta-data=/dev/loop0             isize=256    agcount=4, agsize=32000 blks
         =                       sectsz=512   attr=0
data     =                       bsize=4096   blocks=128000, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096  
log      =internal               bsize=4096   blocks=1200, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=0
realtime =none                   extsz=4096   blocks=0, rtextents=0

Can somebody explain the difference in attr and lazy-count parameters?
Which output is the right one?
