i also dont see any benefit from inlining small files:
this example is me doing a fully fledged prebuilt
gentoo system installation on a fresh HDD from
squashfs image on usb key in under 5 minutes:
with defaults (inlining small files):
# mount -o noatime,compress=lzo /dev/sda2 /mnt/point
# time unsquashfs -f -d /mnt/point/ /dev/sdb2
real 4m39.253s
user 1m37.854s
sys 1m1.433s
# btrfs filesystem show
Label: 'root' uuid: 6fb7104d-8f4a-4f3a-aff8-fdad0a39f569
Total devices 1 FS bytes used 10.05GB
devid 1 size 232.63GB used 14.04GB path /dev/sda2
Btrfs v0.20-rc1
# btrfs filesystem df /mnt/point/
Data: total=10.01GB, used=9.08GB
System, DUP: total=8.00MB, used=4.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=2.00GB, used=992.48MB
Metadata: total=8.00MB, used=0.00
without inline:
# mount -o max_inline=0,noatime,compress=lzo /dev/sda2 /mnt/point
# time unsquashfs -f -d /mnt/point/ /dev/sdb2

i will test "no inlining" for some more time though.
