1,In the code,readdir-ahead didn't package up the readdir request into
a bigger request, it just packaged up the dentries, if the dentries'
size was greater than the request size, the bigger request returned to
the client, wasn't it?
2,The requests from the Readdir-ahead Xlator wind down to next Xlator
,did they send to a server or brodcast to all the servers?
3,As you have said, the preload is in progress, a readdir from
application waits for its completion. And If I change the
buffer(request) size, will the application wait for a long time? Could
it be a stream, the readdir from application fetches dentries in the
buffer, and the readdir-ahead xlator pre-fetches dentries from the
4,When does it can be a larger buffer, like io-cache,which cached the
data/dentries read before? As you know, ls is so slow.
