[PATCH 0/1] fs: remove hpfs filesystem

[Breno Rodrigues Alves]

The HPFS filesystem driver has been orphaned and unmaintained for a
long time.  An RFC on linux-fsdevel stated that HPFS is about to be
removed as it has no remaining users and is no longer supported on
SMP or PREEMPT kernels.  Recent vulnerabilities (e.g.,
CVE-2026-97486) further highlight the lack of maintenance.

This patch removes the driver along with its Kconfig entry,
documentation, and CREDITS entries.  The HPFS_SUPER_MAGIC value in
include/uapi/linux/magic.h is kept for userspace ABI compatibility,
and defconfig cleanups will be sent separately to the respective
architecture maintainers.
