the sdcard file taint propagation didn't work properly

[bobo]

Dear all:
I tried using Taint.addTaintFile , but there are some bugs?

logcat like this:

I/dalvikvm(  299): TaintLog: addTaintFile(42): adding 0x00000002 to 0x00000000 = 0x00000002
D/test xattr(  299): 42:0
I/dalvikvm(  299): TaintLog: addTaintFile(42): adding 0x00000080 to 0x00000000 = 0x00000080
D/test xattr(  299): 42:0

I formatted the SD card img ,such as ext3/ext4,the kernel log show me:

Freeing init memory: 124K
mmc0: new SD card at address e118
mmcblk0: mmc0:e118 SU02G 512 MiB
 mmcblk0: unknown partition table

Anybody could help me?
thank you
