Hi folks,

Please either don't upgrade to zfs-2.1.10 or instead ship a revert of
4b3133e671b958fa2c915a4faf57812820124a7b (2.1.x) /
519851122b1703b8445ec17bc89b347cea965bb9 (master).

See https://github.com/openzfs/zfs/issues/14753 for details, but the
gist is that it's likely a repeat of the kind of problems we saw
in https://github.com/openzfs/zfs/issues/11900.

You can grab the revert we're using in Gentoo from
https://github.com/gentoo/gentoo/commit/a64fff9b8106dec5affc6a9e82bb9cbbb1fe6fec
if you wish.

best,
sam
