Subject: [PATCH v2 1/2] test/efd: fix size of constant
Date: Thu, 24 Feb 2022 15:57:58 +0000	[thread overview]
Message-ID: <20220224155759.819460-1-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <20220224154801.819320-1-pablo.de.lara.guarch@intel.com>

Constant value 1 has a size of 32 bits, and shifting it more than 32 bits
to the left overflows. 1ULL is needed to be able to get a 64-bit value.

Coverity ID: 375846
Fixes: 8751a7e9832b ("efd: allow more CPU sockets in table creation")
