    Subject[2.6.31] Memory leak in SCSI initialization?

    I can see below message appears for 15 times in
    /sys/kernel/debug/kmemleak after processing /init inside initramfs.

    unreferenced object 0xdeadb5c8 (size 32):

    Environment is CentOS 5.3 on i686 .
    The content of /init is shown below.
