The work contained in here adds support for case-insensitive file names lookups in tmpfs. The main difference from other casefold filesystems is that tmpfs has no information on disk, just on RAM, so we can't use mkfs to create a case-insensitive tmpfs. For this implementation, there's a mount option for casefolding. The rest of the patchset follows a similar approach as ext4 and f2fs. The use case for this feature is similar to the use case for ext4, to better support compatibility layers (like Wine), particularly in combination with sandboxing/container tools (like Flatpak). Those containerization tools can share a subset of the host filesystem with an application. In the container, the root directory and any parent directories required for a shared directory are on tmpfs, with the shared directories bind-mounted into the container's view of the filesystem. If the host filesystem is using case-insensitive directories, then the application can do lookups inside those directories in a case-insensitive way, without this needing to be implemented in user-space. However, if the host is only sharing a subset of a case-insensitive directory with the application, then the parent directories of the mount point will be part of the container's root tmpfs. When the application tries to do case-insensitive lookups of those parent directories on a case-sensitive tmpfs, the lookup will fail" * tag 'vfs-6.13.tmpfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: tmpfs: Initialize sysfs during tmpfs init tmpfs: Fix type for sysfs' casefold attribute libfs: Fix kernel-doc warning in generic_ci_validate_strict_name docs: tmpfs: Add casefold options tmpfs: Expose filesystem features via sysfs tmpfs: Add flag FS_CASEFOLD_FL support for tmpfs dirs tmpfs: Add casefold lookup support libfs: Export generic_ci_ dentry functions unicode: Recreate utf8_parse_version() unicode: Export latest available UTF-8 version number ext4: Use generic_ci_validate_strict_name helper libfs: Create the helper function generic_ci_validate_strict_name() |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
