Zone Write Plugging Comes To Linux 6.10 For Better Performance

([Linux Storage] 5 Hours Ago Linux 6.10)


Along with the [1]IO_uring improvements for Linux 6.10, the block subsystem changes have also been merged for this new kernel version.

Notable to the block code updates is another attempt at making long running discards interruptible, adding a partscan attribute to sysfx for helping out systemd, dropping an old throttle low interface, and other updates.

Arguably most interesting with the block updates for Linux 6.10 is introducing support for Zone Write Plugging (ZWP). Zone Write Plugging allows for controlling the ordering of writes to zoned block devices. Zone Write Plugging replaces Zone Write Locking and functions on BIOs rather than requests.

This Zone Write Plugging functionality can greatly improve the performance of zoned storage devices. Those wanting to learn more about the Zone Write Plugging support in general can see [2]the kernel patchwork comments .

phoronix

When alerted to an intrusion by tinkling glass or otherwise, 1) Calm
yourself 2) Identify the intruder 3) If hostile, kill him.

Step number 3 is of particular importance. If you leave the guy alive
out of misguided softheartedness, he will repay your generosity of spirit
by suing you for causing his subsequent paraplegia and seek to force you
to support him for the rest of his rotten life. In court he will plead
that he was depressed because society had failed him, and that he was
looking for Mother Teresa for comfort and to offer his services to the
poor. In that lawsuit, you will lose. If, on the other hand, you kill
him, the most that you can expect is that a relative will bring a wrongful
death action. You will have two advantages: first, there be only your
story; forget Mother Teresa. Second, even if you lose, how much could
the bum's life be worth anyway? A Lot less than 50 years worth of
paralysis. Don't play George Bush and Saddam Hussein. Finish the job.
