Hi,

+Whenever RDMA resource charing occurs, owner rdma cgroup is returned to

Should be: charging instead of charing

+(b) Query resource limit:
+cat /sys/fs/cgroup/rdma/2/rdma.max
+#Output:
+mlx4_0 uctx=max pd=max ah=2 mr=100 mw=max cq=max srq=max qp=10 flow=max
+ocrdma1 uctx=1 pd=5 ah=1 mr=10 cq=10 srq=max qp=20 flow=max flow=max

Is this really so: double"flow=max" at the end of the ocrdma1 line?
(flow=max flow=max)

+5-4. RDMA
+
+The "rdma" controller regulates the distribution and accounting of
+of RDMA resources.

"of of" should be only a single "of"

+         mlx4_1 uctx=1 ah=0 pd=1 cq=4 qp=4 mr=100 srq=0 flow=10
+         ocrdma1 uctx=2 pd=2 ah=2 mr=20 mw=max cq=1 srq=1 qp=10 flow=10

Seems to be inconsistency here: in the first line you have qp=4
*before* srq=0, but in the second line you have qp=10 *after* srq=1.

Keep on the good work!
