Hi, everybody,
I have some questions about FS vnode operations.
I found the filesystems always declare vnode operations by "VNODEOP_SET"
more than once.
For example:
In DEVFS:
VNODEOP_SET(devfs_vnodeop_opv_desc);
VNODEOP_SET(devfs_specop_opv_desc);
In FFS:
VNODEOP_SET(ffs_vnodeop_opv_

I do not know the difference between "+" and "=". why?
Thank you, I got it from 'info gcc'.
It is the reason that "Extended asm supports input-output or read-write
operands. Use the constraint character `+' to indicate such an operand
and list it with the output operands.".

Hi,everybody,
I have one question about GNU ASM syntax.
As I know:
__asm __volatile(
"instructions"
:output
:input
:exception);
In Linux, the restriction of output are "=m","=a", etc.
But I found in FreeBSD, there are "=m" and "+m".
I do not know the difference between "+" and "=". why?

Linux puts kvm at 0xc000, kernel at physical 0x10, etc. There
was a time when you could address all of physical memory just by
direct-mapping the PTEs, since base of 0xc000 means KVM sp

Because it measures the API one way, but the code uses it another.

Thanks a lot Terry, and will you please correct me if I'm wrong, so I
don't mess anything up on a production server? The kernel option in
