+What: /sys/kernel/uids/<uid>/cpu_shares
+Date: December 2007, finally removed in kernel v2.6.34-rc1
+Contact: Dhaval Giani <dhaval@linux.vnet.ibm.com>
+ Srivatsa Vaddagiri <vatsa@linux.vnet.ibm.com>
+Description:
+ The /sys/kernel/uids/<uid>/cpu_shares tunable is used
+ to set the cpu bandwidth a user is allowed. This is a
+ propotional value. What that means is that if there
+ are two users logged in, each with an equal number of
+ shares, then they will get equal CPU bandwidth. Another
+ example would be, if User A has shares = 1024 and user
+ B has shares = 2048, User B will get twice the CPU
+ bandwidth user A will. For more details refer
+ Documentation/scheduler/sched-design-CFS.rst
