Subject: [patch 01/25] khugepaged: selftests: fix timeout condition in wait_for_scan()
Date: Wed, 10 Jun 2020 18:41:22 -0700	[thread overview]
Message-ID: <20200611014122.khjJlVhQh%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200610184053.3fa7368ab80e23bfd44de71f@linux-foundation.org>

Subject: khugepaged: selftests: fix timeout condition in wait_for_scan()

The loop exits with "timeout" set to -1 and not to 0 so the test needs to
be fixed.

Fixes: e7b592f6caca ("khugepaged: add self test")
