This patchset updates the submodule to the recently released version 2.4.0:
https://github.com/openzfs/zfs/releases/tag/zfs-2.4.0

from the changelog the following changes seem interesting relevant:
* using special devices for the ZIL (if no dedicated slog device is
  configured)
* small blocks of zvols (in addtition to regular filesystem datasets) can
  now be written to the special vdevs (this is guarded by the dataset
  property sepcial_small_blocks)
* arc_summary and arcstat have been renamed to zarcsummary and zarcstat
  respectively (the latter calls for adaptation of our system-reports for
  PVE at least)

the patches for the soname bump of libzfs and libzpool, as well as the
adaptations to the debian folder follow the changes done in
debian-upstream:
https://salsa.debian.org/zfsonlinux-team/zfs.git

this was minimally tested on 2 VMs I have. (one running the new userspace
and new kernel modules, the other pinned to a kernel 6.14 with zfs 2.3).

This should fix https://bugzilla.proxmox.com/show_bug.cgi?id=7199
(we have a few independent reports of users running into hangs when
accessing snapshots through the controldir (.zfs/snap/<snapname>).
I'll check if the fixes for 7199 are easily backported to ZFS 2.3 as well.
