Low Severity
Scatter-gather tables are mechanism used for high performance I/O on DMA devices. Enable this to turn on checks on scatter-gather tables. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_DEBUG_SG
, run the following command:
grep CONFIG_DEBUG_SG /boot/config-*
For each kernel installed, a line with value "y" should be returned.
