Linux Storage and Filesystem Workshop, day 2Linux Storage and Filesystem Workshop, day 2Posted Apr 11, 2009 0:27 UTC (Sat) by neilbrown (subscriber, #359)Parent article: Linux Storage and Filesystem Workshop, day 2 readdirplus() The creation of this system call looks like an opportunity to leave some old mistakes behind. So, for example, it will not support seeking within a directory. There is some irony here. The name "readdirplus" comes from NFS - NFSv3 introduced a READDIRPLUS protocol request for exactly the same reason. And to support NFS, you absolutely need to be able to seek within a directory. It is conceivable that some .x version of NFSv4 might remove this requirement. But until we agree to stop supporting NFSv3, we need to be able to seek within a directory.
