Description Mohit Agrawal 2020-11-18 04:00:37 UTC

io-stats xlator declares a ios_sample_buf_size 64k object(10M) per xlator
but in case of sample_interval is 0 this big buffer is not required so
declare the default value only while sample_interval is not 0.The new
change would be helpful to reduce RSS size for a brick and shd process
while the number of volumes are huge especially in brick_mux environment.
