Pull erofs updates from Gao Xiang:
"In this cycle, Intel QAT hardware accelerators are supported to
improve DEFLATE decompression performance. I've tested it with the
enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids
bare-metal server and a PL0 ESSD, and the sequential read performance
even surpasses LZ4 software decompression on this setup.

In addition, a `fsoffset` mount option is introduced for file-backed
mounts to specify the filesystem offset in order to adapt customized
container formats.

And other improvements and minor cleanups. Summary:

- Add a `fsoffset` mount option to specify the filesystem offset

- Support Intel QAT accelerators to boost up the DEFLATE algorithm

- Initialize per-CPU workers and CPU hotplug hooks lazily to avoid
unnecessary overhead when EROFS is not mounted

- Fix file handle encoding for 64-bit NIDs

- Minor cleanups"

erofs: support DEFLATE decompression by using Intel QAT

This patch introduces the use of the Intel QAT to offload EROFS data
decompression, aiming to improve the decompression performance.

A 285MiB dataset is used with the following command to create EROFS
images with different cluster sizes:
$ mkfs.erofs -zdeflate,level=9 -C{4096,16384,65536,131072,262144}

Fio is used to test the following read patterns:
$ fio -filename=testfile -bs=4k -rw=read -name=job1
$ fio -filename=testfile -bs=4k -rw=randread -name=job1
$ fio -filename=testfile -bs=4k -rw=randread --io_size=14m -name=job1

Here are some performance numbers for reference:

Merge tag 'erofs-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
"In this cycle, we add file-backed mount support, which has has been a
strong requirement for years. It is especially useful when there are
thousands of images running on the same host for containers and other
sandbox use cases, unlike OS image use cases.

Without file-backed mounts, it's hard for container runtimes to manage
and isolate so many unnecessary virtual block devices safely and
efficiently, therefore file-backed mounts are highly preferred. For
EROFS users, ComposeFS [1], containerd, and Android APEXes [2] will
directly benefit from it, and I've seen no risk in implementing it as
a completely immutable filesystem.

The previous experimental feature "EROFS over fscache" is now marked
as deprecated because:

- Fscache is no longer an independent subsystem and has been merged
into netfs, which was somewhat unexpected when it was proposed.

- New HSM "fanotify pre-content hooks" [3] will be landed upstream.
These hooks will replace "EROFS over fscache" in a simpler way, as
EROFS won't be bother with kernel caching anymore. Userspace
programs can also manage their own caching hierarchy more flexibly.

Once the HSM "fanotify pre-content hooks" is landed, I will remove the
fscache backend entirely as an internal dependency cleanup. More
backgrounds are listed in the original patchset [4].

In addition to that, there are bugfixes and cleanups as usual.

Summary:

- Support file-backed mounts for containers and sandboxes

- Mark the experimental fscache backend as deprecated

- Handle overlapped pclusters caused by crafted images properly

- Fix a failure path which could cause infinite loops in
z_erofs_init_decompressor()

- Get rid of unnecessary NOFAILs

- Harmless on-disk hardening & minor cleanups"
