      Description

      We implement a new feature which provides new APIs and utils for senior users and smart applications to give advices about the access pattern of Lustre file so as to improve the data/metadata access peformance. It has a similar idea with fadvise64_64(2) or posix_fadvise(2), yet can pass specical advices directly through Lustre client to server/storage side.

      Some tests show that this feature might help us to get performance improvement for some application by giving proper advices in advance.
