Subject: mm/codetag: fix arg in pgalloc_tag_copy alloc_tag_sub
Date: Tue, 22 Oct 2024 23:24:40 +0000
alloc_tag_sub() takes bytes as opposed to number of pages as argument.
Currently pgalloc_tag_copy() passes the number of pages. This fix passes
the correct unit, which is the number of bytes allocated.
