Description Pranith Kumar K 2012-09-27 03:19:52 UTC 
Description of problem:
Entry self-heal does lookups on all the entries that are read in readdir. More the size of readdir more number of lookups happen in parallel. It is observed that it leads to HUGE cpu spikes rendering everything else on the system unusable. There should be an option to control this readdir size.
