* quick-read: implement qr_openRaghavendra G2009-07-161-0/+18
| | | | | | | | - The file is opened actually only if it is not cached already in lookup. This adds responsibility for fops operating on fds to make sure that a valid fd actually opened on a file is used to complete the fop. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* Implementing quick-read translator.Raghavendra G2009-07-161-0/+50
lookup can fetch the entire file in xattr dictionary using the key "glusterfs.content". We set the maximum size of the file that can be fetched so in the xattr_req dictionary using the same key. If file-size is less than or equal to the value set in dictionary, the content is stored in the dictionary using same key in lookup_cbk. For small files, we can do an optimization wherein we do not really send the calls open, read and close to the storage translators. Instead there can be an xlator which fakes open, read and close calls. For reads, it sends the data it has cached during lookup and hence saving the time for open, read and close calls to reach storage translators (this time can be significant if calls have to go through network to reach storage translator).
