With mount option "mba_MBps", we could enable MBA Software Controller (mba_sc) to specify MBA memory bandwidth in unit MBps (Mega Bytes per second). See details in Documentation/x86/resctrl_ui.txt.
Commit 23bf1b6be9c2 ("kernfs, sysfs, cgroup, intel_rdt: Support fs_context") changes the mount option from "mba_MBps" to "mba_mpbs" by mistake.
Change back from "mba_mpbs" to "mba_MBps", and rename Opt_mba_mpbs to Opt_mba_mbps.
