[Andrew Morton]

The quilt patch titled
     Subject: lib/test_hmm: use kvfree() to free kvcalloc() allocations
has been removed from the -mm tree.  Its filename was
     lib-test_hmm-use-kvfree-to-free-kvcalloc-allocations.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/test_hmm: use kvfree() to free kvcalloc() allocations
Date: Wed, 13 May 2026 16:25:25 +0800

Coccinelle scripts/coccinelle/api/kfree_mismatch.cocci reports
the following warnings:

  lib/test_hmm.c:1256:15-16: WARNING kvmalloc is used to allocate this memory at line 1191
  lib/test_hmm.c:1257:15-16: WARNING kvmalloc is used to allocate this memory at line 1196

Fix this by replacing kfree() with kvfree() to correctly handle the
vmalloc() fallback path of kvcalloc().
