[Gluster-users] Warning messages in client logs

[Prasun Gera]

I have isolated the issue to be related to readdirp. Both the clients where
I see the messages are running relatively newer kernels (3.13+), and by
default the kernel readdirp support is enabled. If I mount
with use-readdirp=no, I don't see the Warning messages. Is this a known
issue ?
