It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Since it can't be paged out, it is never actually enqueued in a paging queue. Nonetheless, passing PQ_INACTIVE to vm_page_unwire() creates the appearance that the page "frame" is being enqueued in the inactive queue. As of r288122, we can avoid this false impression by passing PQ_NONE. 2016-05-03T03:41:25Z Pedro F.

This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted. 2016-04-10T23:07:00Z Pedro F.

The new sendfile is the code that Netflix uses to send their multiple tens of gigabits of data per second. The new implementation features asynchronous I/O, when I/O operations are launched, but not awaited to be complete. An explanation of why such behavior is beneficial compared to old one is going to be too long for a commit message, so we will skip it here. Additional features of new syscall are extra flags, which provide an application more control over data sent. The SF_NOCACHE flag tells kernel that data shouldn't be cached after it was sent. The SF_READAHEAD() macro allows to specify readahead size in pages. The new syscalls is a drop in replacement. No modifications are required to applications. One can take nginx binary for stable/10 and run it successfully on head. Although SF_NODISKIO lost its original sense, as now sendfile doesn't block, and now means something completely different (tm), using the new sendfile the old way is absolutely safe.

Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.
