Subject: [PATCH] net/handshake: Squelch allocation warning during Kunit test
From: Chuck Lever <chuck.lever@...cle.com>
The "handshake_req_alloc excessive privsize" kunit test is intended
to check what happens when the maximum privsize is exceeded. The
WARN_ON_ONCE_GFP at mm/page_alloc.c:4744 can be disabled safely for
this allocator call site.
Reported-by: Linux Kernel Functional Testing <lkft@...aro.org>
Fixes: 88232ec1ec5e ("net/handshake: Add Kunit tests for the handshake consumer API")
Signed-off-by: Chuck Lever <chuck.lever@...cle.com>
