Firstly, thankyou for your reply, However, I still think you are mistaken.
"There is no double re-mounting of the filesystem".
I try again, but in case my writing isn't convincing. Let's agree to disagree,
until
I have more conclusive proof, either to what confirm what you say, or what I
say.

Hi Ming,
Thank you for looking into this.
let me loop in Alasdair, Mike and Zdenek for further comment on LVM stuff
Thanks,

It was reported that allocating pages for the write buffer in dm-crypt
causes measurable overhead [1].
This patch changes dm-crypt to allocate compound pages if they are
available. If not, we fall back to the mempool.

Older kernels have these checks in a separate function called
blk_cloned_rq_check_limits, which carries the following comment:

Hi
From lvm2 POV - couple clarifications - to let thin-pool auto-extend - user
has to configure:
Besides caching at the dm layer, there is caching at the filesystem
layer (files, directories and other stuff). The caching at the DM
layer is not the issue.
If rootfs mounts the dm-device someplace as a
(ntfs)filesystem(readonly), and then later you also mount that same
(ntfs)filesystem
Firstly, thankyou for your reply. I'm not a kernel expert, so I value what you
say.
but as I raised the issue I felt I had to defend the usefulness, userbase and
the need.

Hi guys,
I encountered a hang issue on a s390x system. The tested kernel is
not preemptible and booting with "nr_cpus=1"
The test steps:
umount /home
lvremove /dev/rhel_s390x-kvm-011/home
## uncomment "snapshot_autoextend_threshold = 70" and
"snapshot_autoextend_percent

Correct.
