From: Ido Schimmel Date: Wed, 10 Apr 2019 06:58:13 +0000 (+0000) Subject: mlxsw: core: Do not use WQ_MEM_RECLAIM for EMAD workqueue X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab533b384ecfd88b888ca269479735d485f5fcaa;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mlxsw: core: Do not use WQ_MEM_RECLAIM for EMAD workqueue [ Upstream commit a8c133b06183c529c51cd0d54eb57d6b7078370c ] The EMAD workqueue is used to handle retransmission of EMAD packets that contain configuration data for the device's firmware. Given the workers need to allocate these packets and that the code is not called as part of memory reclaim path, remove the WQ_MEM_RECLAIM flag.
