Hi all,

In a conversation between me, Milind and Csaba, Milind pointed out fadvise(2) 
[1] and its potential benefits to Glusterfs' caching translators like 
read-ahead etc. After discussing about it, we agreed that our performance 
translators can leverage the hints to provide better performance. Now the 
question is how commonly applications actually provide hints? Is it something 
that is used quite frequently? If yes, we can think of implementing this in 
glusterfs (probably kernel-fuse too?). If no, there is not much of an advantage 
in spending our energies here. Your inputs will help us to prioritize this
