Correct, you can pass along the size, and if it's not large enough

Correct, you can pass along the size, and if it's not large enough
try again... Less than ideal...
Is there a way to malloc
I have a problem and I can't quite figure out where to look. This is what Im
doing:
I have an IOCTL to read a block of data, but the data is too large to return
via ioctl. So to get the data,
I allocate a block in a kernel module:
foo = malloc(1024000,M_DEVBUF,M_WAITOK);
I pass up a pointer
