When we load an ELF file (kernel or module) we do seek(2) a lot to parse/load the different sections of the ELF file. Protocol like TFTP suffers a lot from this as there is no resume or a way to start the tranfer from a specified offset in the file. fs_preload is added to help those protocol. Call preload just after opening the ELF file that we need to load so the underlying method can cache the hole file and then read/lseek operations are faster.
