Add the multiblock allocator (mballoc.c) to the build. This implements the ext4 block allocation routines. Stubs added for: - Per-CPU operations (simplified to single-threaded) - XArray operations - RCU list operations - Block device properties - Various trace functions - Atomic operations (atomic_sub, atomic64_sub, atomic_inc_return) - WARN_RATELIMIT, folio_get, array_index_nospec - seq_operations for procfs - DEFINE_RAW_FLEX macro Remove stub functions that are now properly implemented: - ext4_mb_new_blocks - ext4_free_blocks - ext4_discard_preallocations - ext4_mb_mark_bb Add ext4_fc_replay_check_excluded stub for fast commit replay. Add file member to struct seq_file for procfs compatibility. Co-developed-by: Claude Opus 4.5 <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
