Subject: mm/vmalloc: fix incorrect size reporting on allocation failure
Date: Mon, 2 Mar 2026 12:47:39 +0100

When __vmalloc_area_node() fails to allocate pages, the failure message
may report an incorrect allocation size, for example:

  vmalloc error: size 0, failed to allocate pages, ...

This happens because the warning prints area->nr_pages * PAGE_SIZE.  At
this point, area->nr_pages may be zero or partly populated thus it is not
valid.

Report the originally requested allocation size instead by using
nr_small_pages * PAGE_SIZE, which reflects the actual number of pages
being requested by user.
