Subject: [GIT PULL] overlayfs updates for 6.18
Hi Linus,
Please pull overlayfs updates for 6.18.
This branch has been sitting in linux-next for a few weeks,
but I added some RVB last week.
It has gone through the usual overlayfs test routines.
The branch merges cleanly with master branch of the moment.
Note that there is a small change to fs.h in this PR for the
sb encoding helpers.
This change is reviewed by Gabriel and Christian has agreed that I will
merge it through the ovl tree.
Thanks,
Amir.

ovl: make sure that ovl_create_real() returns a hashed dentry (2025-09-23 12:29:36 +0200)
----------------------------------------------------------------
overlayfs updates for 6.18
- Work by André Almeida to support case-insensitive overlayfs
Underlying case-insensitive filesystems casefolding is per directory,
but for overlayfs it is all-or-nothing. It supports layers where
all directories are casefolded (with same encoding) or layers where
no directories are casefolded.
- A fix for a "bug" in Neil's ovl directory lock changes,
which only manifested itself with casefold enabled layers
which may return an unhashed negative dentry from lookup.
