Merge tag 'vfs-7.0-rc1.initrd' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs initrd removal from Christian Brauner:
 "Remove the deprecated linuxrc-based initrd code path and related dead
  code. The linuxrc initrd path was deprecated in 2020 and this series
  completes its removal. If we see real-life regressions we'll revert.

  The core change removes handle_initrd() and init_linuxrc() — the
  entire flow that ran /linuxrc from an initrd, pivoted roots, and
  handed off to the real root filesystem. With that gone, initrd_load()
  becomes void (no longer short-circuits prepare_namespace()),
  rd_load_image() is simplified to always load /initrd.image instead of
  taking a path, and rd_load_disk() is deleted.

  The /proc/sys/kernel/real-root-dev sysctl and its backing variable are
  removed since they only existed for linuxrc to communicate the real
  root device back to the kernel.

  The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped,
  and noinitrd and ramdisk_start= gain deprecation warnings.

  Initramfs is entirely unaffected. The non-linuxrc initrd path
  (root=/dev/ram0) is preserved but now carries a deprecation warning
  targeting January 2027 removal"
