Subject: [PATCH 1/3] block: cgroups, kconfig, build bits for BFQ-v7r11-4.4.0
|
||||
|
||||
Update Kconfig.iosched and do the related Makefile changes to include
|
||||
kernel configuration options for BFQ. Also increase the number of
|
||||
policies supported by the blkio controller so that BFQ can add its
|
||||
own.
