  Hi Linus,

Could you consider this pull request for 6.4-rc1?

In this cycle, sub-page block support for uncompressed files is
available.  It's mainly used to enable golden 4k-block images on arm64
with 16/64k pages.  In addition, end users could also use this feature
to build a manifest to directly refer to golden tar data.

Besides, long xattr name prefix support is also introduced in this
cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
xattrs).  It's useful for erofs + overlayfs combination (like Composefs
model):  the image size is reduced by ~14% and runtime performance is
also slightly improved.

Others are random fixes and cleanups as usual.  All commits have been
in -next for a while and currently there is only a minor merge conflict
with the vfs-idmapping tree [1].  Christian also mentioned this in the
related pull request.

Thanks,
Gao Xiang
