Subject: [PATCH-next 1/5] lib/test_vmalloc.c: remove two kvfree_rcu() tests
Date:   Fri,  2 Apr 2021 22:22:33 +0200
Message-Id: <20210402202237.20334-1-urezki@gmail.com>

Remove two test cases related to kvfree_rcu() and SLAB. Those are
considered as redundant now, because similar test functionality
has recently been introduced in the "rcuscale" RCU test-suite.
