Subject[PATCH] nvme-pci: disable write zeroes on Kingston SSD
Date
signed-off-by: Xander Li <xander_li@kingston.com.tw>

Kingston SSDs do support NVMe Write_Zeroes cmd but take long time to process.
The firmware version is locked by these SSDs, we can not expect firmware improvement, so disable Write_Zeroes cmd.
