/*
* read.c - FUSE read function
*
* Created on: Mar 14, 2012
* Author: mg
*
Read data from an open file
*
* Read should return exactly the number of bytes requested except
* on EOF or error, otherwise the rest of the data will be
* substituted with zeroes. An exception to this is when the
* 'direct_io' mount option is specified, in which case the return
* value of the read system call will reflect the return value of
* this operation.
*
* Changed in version 2.2
