[PATCH v2 4/5] lib/Kconfig.debug: properly split hash test kernel entries

From: Isabella Basso
Date: Sun Sep 26 2021 - 18:34:24 EST


Split TEST_HASH so that each entry only has one file.

Note that there's no stringhash test file, but actually
<linux/stringhash.h> tests are performed in lib/test_hash.c.
