Hello!
I got a question reggarding the way small data is saved on bfs used in
haiku. Dominic on it's book says:
"tha bytes of the name begin in the name field and continue from there. The
attribute value (its data) is stored immediately following the bytes of the
name" (pag 61)
Now i'm taking a look at haiku alpha image (in file
haiku-r1alpha1-image.zip), and for example lets take the Tracker file inode
( inode number 262164, on disk plain offset 0x2000A000h):
2000A0E0 40 35 42 28 00 00 00 00 52 54 53 43 01 00 07 00 13 00 00
00 54 72 61 63 6B 65 72 00 53 4D 49 4D

00 53 4D 49 4D 0C 00 1A 00 42 45 4F 53

If we focus on offset 200A0E8 we got the first small_data, but it's data is
not immediately after the value. The happens with the next value.
Does haiku save small data in a different way, or i misunderstood something
on Dominic's book??
Thanks!!
