+++ This bug was initially created as a clone of Bug #2120497 +++ Description of problem: wsp(MB/s) field in cephfs-top shows wrong and negative values changing infinitely. Steps to reproduce: 1. Create two filesystems and mount them as client1 and client2. 2. run cephfs-top. 3. Write something to client1 only. 4. Both client1 and client2 shows changing wsp values, even if there is no IO in client2. client1 shows changing positive values and client2 shows changing negative values. This continues infinitely since the write starts and doesn't stop when the write ends. However, this issue is not observed in 'perf stats' output. Version-Release number of selected component (if applicable): 5.3z1 How reproducible: Always Steps to reproduce: 1. Create two filesystems and mount them as client1 and client2. 2. run cephfs-top. 3.

Actual results: wsp(MB/s) field in cephfs-top shows wrong and negative values changing infinitely. Expected results: wsp(MB/s) field in cephfs-top show calculated values correctly and only when there is an IO on a particular client. Additional info:
