From 6a734e62f1557de3449c689effd2b37066ea34eb Mon Sep 17 00:00:00 2001

Subject: [PATCH] malloc: Fix transposed arguments in sysmalloc_mmap_fallback
call
git commit 0849eed45daa ("malloc: Move MORECORE fallback mmap to
sysmalloc_mmap_fallback") moved a block of code from sysmalloc to a
new helper function sysmalloc_mmap_fallback(), but 'pagesize' is used
for the 'minsize' argument and 'MMAP_AS_MORECORE_SIZE' for the
'pagesize' argument.
Fixes: 0849eed45daa ("malloc: Move MORECORE fallback mmap to sysmalloc_mmap_fallback")
