Subject: [PATCH net-next v4 0/2] net: hinic: fix bugs about dev_get_stats
Date: Tue,  5 Jul 2022 19:22:21 +0800	[thread overview]
Message-ID: <cover.1657019475.git.mqaio@linux.alibaba.com> (raw)

These patches fixes 2 bugs of hinic driver:
- fix bug that ethtool get wrong stats because of hinic_{txq|rxq}_clean_stats() is called
- avoid kernel hung in hinic_get_stats64() 

See every patch for more information. 

Changes in v4:
- removed meaningless u64_stats_sync protection in hinic_{txq|rxq}_get_stats
- merged the third patch in v2 into first one

Changes in v3:
- fixes a compile warning reported by kernel test robot <lkp@intel.com>

Changes in v2:
- fixes another 2 bugs. (v1 is a single patch, see: https://lore.kernel.org/all/07736c2b7019b6883076a06129e06e8f7c5f7154.1656487154.git.mqaio@linux.alibaba.com/).
- to fix extra bugs, hinic_dev.tx_stats/rx_stats is removed, so there is no need to use spinlock or semaphore now.
