knuxify 96a30fb31b kconfigcheck: make BTRFS and F2FS modules 
Initially, these were switched to built-ins as they were included in
the default initramfs, which can have a worse compression ratio
than the kernel itself (e.g. Exynos 4 kernel uses xz for kernel, gzip
(pmbootstrap default) for initramfs).

Since f45319dc, however, these have been moved to initramfs-extra;
as such, they don't get built into the initramfs on devices that use
create_initfs_extra. They are now safe to move to modules - this
lets us save ~2MB on space-constrained devices.

Aelin 06318bcfec kconfigcheck: Drop options redundant with 5.18 community baseline 
As per https://docs.postmarketos.org/pmaports/main/kconfigcheck.html and
considering that today is the beginning of June 2026, the baseline for
community kconfig checks is Linux 5.18, so we can remove the redundant
CONFIG_ASHMEM enablement in the waydroid category for kernels older than
5.18.

Aster Boese 6ecd7f6d43 kconfigcheck: move VFAT_FS to category:default 
All but 10 kernels in downstream and 1 in testing support VFAT_FS already.
FAT32, which VFAT_FS supports, is proposed with
https://gitlab.postmarketos.org/postmarketOS/pmbootstrap/-/merge_requests/2869
to become the default filesystem for pmOS_boot. Since so many kernels already
support this option and the FAT filesystems are so common, there is no reason
not to include VFAT_FS by default. VFAT_FS only increases kernel size by 10kb,
so it does not impact boot partition space in any meaningful way.

Aelin 4402d4a28e kconfigcheck: Require support for Yama 
This lets us prohibit non-ancestor ptrace access to running processes
and their credentials via sysctl kernel.yama.ptrace_scope=1.

Yama stacks correctly with SELinux. Arch Linux enables it and sets
ptrace_scope=1 by default, see https://wiki.archlinux.org/title/Security#ptrace_scope.

Note that SELinux also has the deny_ptrace mechanism to achieve similar
things, but we're not shipping SELinux at the moment and we can opt to
switch to deny_ptrace for enforcing this in the future if desired.

See https://docs.kernel.org/admin-guide/LSM/Yama.html for more information.

Aster Boese 921c30190b kconfigcheck: add CONFIG_RUST=y to category:rust 
category:rust was actually not added to *enable* Rust support in the kernel,
but to add options needed by kernels that had *already* enabled Rust. Since
the category was meant for kernels with Rust enabled, enabling Rust support
with the category makes sense and fits better with the category name to clear
up any confusion kernel package maintainers may have.

CONFIG_CRYPTO_CTS is built-in if CONFIG_FS_ENCRYPTION is enabled, which
it is by default on loongarch64, which is reasonable.

CONFIG_NFSD is also built-in on some architectures, which causes
CONFIG_RPCSEC_GSS_KRB5 to be built-in rather than a module. We could
either force disable NFSD, which is not great, or just build it as a
module, which is what I opted for.
