Are you running an old kernel (pre-5.0 e.g.)?

Hi,
I'm trying to debug the performance of rsync reading from a Windows 2012
R2 share mounted readonly in CentOS 7. I tried to use cifsiostat, which
doesn't print any stats. I looked into /proc/fs/cifs/Stats and saw that
it contains mostly "0" for counters (I would expect to see some numbers
for eg "Reads"). What am I doing wrong?
options from /proc/mounts are
ro,relatime,vers=3.0,cache=strict,username=foo,domain=xxx,uid=1706,forceuid,gid=1676,forcegid,addr=10.110.81.122,file_mode=0660,dir_mode=0770,soft,nounix,serverino,mapposix,rsize=61440,wsize=1048576,echo_interval=60,actimeo=1
thx
Matthias
