I'd argue it isn't flawed for the measuring it is supposed to do - namely

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

Yes.

The results you get are not predictive of the code that you are
going to be running.

As a rule, swap should be at least physical memory size + 64K on
any system that you need to be able to get a system dump from,
since it needs to dump physical RAM. If you are not worried about
the machine falling over, then you can ignore that.

A question arises. The value 256 (1G KVA space) acts as a default for any
system installation, not depending of real phisical memory size. So for
any server with RAM less than 2G (which is a majority I presume) the KVA
space occupies more

I have one question about GNU ASM syntax.

: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?
Thank you!
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..

I have some questions about FS vnode operations.
I found the filesystems always declare vnode operations by VNODEOP_SET

For example:
