It sets up the remapping for the\noverwrite_bio but then drops it immediately without submission, causing\nwrite operations to hang.\n\nFix by adding a new invalidate_committed() continuation that submits\nthe remapped writes to the cache origin after metadata commit completes,\nwhile using the overwrite_endio hook to ensure proper completion\nsequencing. This maintains existing coherency. Also improve error\nhandling in invalidate_complete() to preserve the original error status\ninstead of using bio_io_error() unconditionally."
