XFS Zone Allocator No Longer Experimental With Linux 7.2

([Linux Storage] 5 Hours Ago XFS + Zoned Storage Devices)


The XFS file-system updates for the [1]Linux 7.2 kernel aren't too notable with the exception of its zone allocator being promoted from behind its previously-experimental flag.

The XFS zone allocator is used for supporting zoned storage devices like shingled magnetic recording (SMR) and zoned namespace (ZNS) SSDs where writes must be done sequentially from start to finish. The XFS zone allocator has been part of the kernel for a while to comply with the zoned device constraints while now for Linux 7.2 it's no longer considered experimental. Again, just relevant for SMR and ZNS type zoned storage devices.

Other than that the [2]XFS merge for Linux 7.2 is just bringing some fixes and minor alterations.

"I don't know what you mean by 'glory'," Alice said.
Humpty Dumpty smiled contemptuously. "Of course you don't --
till I tell you. I meant 'there's a nice knock-down argument for you!'"
"But glory doesn't mean 'a nice knock-down argument'," Alice
objected.
"When I use a word," Humpty Dumpty said, in a rather scornful
tone, "it means just what I choose it to mean -- neither more nor less."
"The question is," said Alice, "whether you can make words mean
so many different things."
"The question is," said Humpty Dumpty, "which is to be master --
that's all."
