sys/kern kern_malloc.c
Log:
MFC: sys/kern/kern_malloc.c 1.150
In realloc(9), determine size of the original block based on
UMA_SLAB_MALLOC flag.
In some circumstances (I observed it when I was doing a lot of reallocs)
UMA_SLAB_MALLOC can be set even if us_keg != NULL.
If this is the case we have wonderful, silent data corruption, because less
data is copied to the newly allocated region than should be.
