[pve-devel] [PATCH zfsonlinux 0/2] update to 2.2.1

[pve-devel] [PATCH zfsonlinux 0/2] update to 2.2.1

[Stoiko Ivanov]

zfs-2.2.1 was released yesterday.
We've already picked all critical patches (potentially involving dataloss)
and a few cosmetic ones.

quickly skimming through the changelog adds - nothing stands out that
sounds particularly scary w.r.t. regressions, but also nothing that we
missed until now. Some performance improvments are still missin in our
current version.

minimially tested on 2 VMs with a few containers with replication.

Stoiko Ivanov (2):

-Subject: [PATCH] zvol: Remove broken blk-mq optimization
-
-This fix removes a dubious optimization in zfs_uiomove_bvec_rq()
-that saved the iterator contents of a rq_for_each_segment().  This
-optimization allowed restoring the "saved state" from a previous
-rq_for_each_segment() call on the same uio so that you wouldn't
-need to iterate though each bvec on every zfs_uiomove_bvec_rq() call.
-However, if the kernel is manipulating the requests/bios/bvecs under
-the covers between zfs_uiomove_bvec_rq() calls, then it could result
-in corruption from using the "saved state".  This optimization
-results in an unbootable system after installing an OS on a zvol
-with blk-mq enabled.

-This gets around UBSAN errors when using arrays at the end of

-arrays and disables UBSAN checking on certain modules.

-Subject: [PATCH] Fix block cloning between unencrypted and encrypted datasets
-
-Block cloning from an encrypted dataset into an unencrypted dataset
-and vice versa is not possible. The current code did allow cloning
-unencrypted files into an encrypted dataset causing a panic when
-these were accessed. Block cloning between encrypted and encrypted
-is currently supported on the same filesystem only.
