CVS commit: src/sys/ufs/lfs

["Konrad Schroder" <perseant%netbsd.org@localhost>]

Module Name:    src
Committed By:   perseant
Date:           Mon Sep 15 04:14:59 UTC 2025

Modified Files:
        src/sys/ufs/lfs: lfs.h lfs_accessors.h lfs_alloc.c

Log Message:
If setting the head (or tail) of the inode free list to LFS_UNUSED_INUM, also
set the tail (resp. head) to LFS_UNUSED_INUM, as the list is now empty.

Add a check to ensure that lfs_valloc_fixed will always terminate, even
if the free list should contain a loop.  Extend the ifile at the end if it
is empty, to match the assumption of lfs_valloc() that the free list is
never empty.

Needed for roll-forward.
