File 0010-nvme-cli-add-support-of-RAE.patch of Package nvme-cli.10367
From: Alexey Timofeyev <alexey.timofeyev@sk.com> Date: Thu, 28 Jun 2018 17:33:05 +0000 Subject: [PATCH] nvme-cli: add support of RAE Git-commit: 97ca8c0d1008aa640e848d7606e85e0828c1cf2d References: bsc#1099018 Currently telemetry-log cannot retain content of corresponding log page as RAE is not set. This patch adds RAE bit support into routines to retrieve log pages.
