I've been mulling for some time to just remove non linear mappings.
AFAIK they were only useful on 32bit and are obsolete and could be
emulated with VMAs instead.



mull: 熟慮する

だけど、日本語のニュアンス的には non linear mappingのコードを消すかどうかをずっと
迷ってるんだよねー。ぐらいか

日本的ないいまわしですな。メモ

今日も某所で英語のお勉強

痛車とかShaorinへの愛とかについて語ってる

I have family, who need peaceful life without being finger-pointed at their back....


英語でも後ろ指を指されるっていうんだ!勉強した!


英語では to talk about someone behind their back が辞書に載っている慣用句ですが、文字通り後ろ指を指すという表現をご近所のネイティブのお爺さんが言っておりました。

Just a moment! は、『待てこら!』『ちょおっとまったあああ!』という意味で、ゆのかさんの使い方はネイティブと言えます。

Just a moment, folks. We are drifting out from our focus! 『みなさん、ちょっと待ってください。議題から逸れています』と会議で発言するとかっこいい。

Wait a minute! のほうが Just a moment! よりキツい感じ。後者は会議中に言われてもたいしてむっとしませんが、前者だと敵を作るかも。




ほむほむ。「マテやゴルァ(゚Д゚ )」か。だいたい分かった。勉強になるなー
今後ビジネスシーンで使うかどうかはともかくとして

behavior は普通 uncountable noun で、単数しかとらず、動詞は is です。私の例文のようにあえて behaviors というと『諸処の所行』という、コミカルな表現です。



勉強になるなー XD

and can we please stop jumping the gun here and going past the subsystem
maintainers. I think this happens a little bit too much lately.

jumping the gun でフライングの事。ここではサブシステムメンテナを飛び越えてパッチがマージされていく事に抗議している

まあ、ようするにDiscard Requestはまだまだ揉めていますよ。って事なんだけど

Hi Christoph,

Thanks for the info.

Yes, in practice TRIM seems a huge disappointment: is there a device on
which it is really implemented, and not more trouble than it's worth?

I'd been waiting for OCZ to get a Vertex 1.4* firmware out of Beta
before looking at swap discard again; but even then, the Linux ATA
support is still up in the air, so far as I know.

You don't mention swap's discard of the whole partition (or all
extents of the swapfile) at swapon time: do you believe that usage
is okay to retain? Is it likely on some devices to take so long,
that I ought to make it asynchronous?

Assuming that initial swap discard is good, I wonder whether just
to revert the discard of swap clusters for now: until such time as
we find devices (other than mtd) that can implement it efficiently.

If we do retain the discard of swap clusters, under something more
than an #if 0, any ideas for what I should make it conditional upon?

Something near /sys/block/sda/queue/rotational (nicely rw these days)
seems appropriate: any chance of a /sys/block/sda/queue/discard_is_useful?
I think I'd prefer that to a new option to swapon.

Or is there a sensible measurement I could make in swapfile.c: for
example, does discard of a range complete faster than write of the
same range? (But my guess is that those devices we'd want to avoid
discard on, would give erratic answers to any such test; never mind
the noise of what other I/Os are concurrent to the same device.)

Something I should almost certainly revert: at one stage I made the
non-rotational case spread its swapping evenly over the partition,
in case the device's wear-levelling was inadequate (localized).

But now I think it's better to ignore that possibility, and anchor
swapping to the start of the partition just as in the rotational case:
in the rotational case it's done to minimize seeking, in the non-
rotational case it would be to minimize encroaching upon that
initially discarded total extent.
