when scsi init, slabs_free list of cache size-64 corrupts. but i don't find

anywhere concerned with this corruption, the slab code is logically correct.

 

next of slabs_free modified by somewhere

malloc_sizes[1].cs_cachep.nodelists[0].slabs_free = {next = 0x2002c48, prev =

0x2002cb0}

This issue is also seen when kernel configured with sdiommc on bf548 board.

it was a bug of strncpy while copying a NULL string

if string length is zero just jump to the end.

Yes, it is fixed and boots up now. Close.
