Last year, as part of the Google Summer of Code program and with the mentoring help of Mark Shellenbaum, I've already ported ZFS to Linux as a userspace filesystem (implemented on top of the FUSE framework). You can go to http://www.wizy.org/wiki/ZFS_on_FUSE for details. The work I was doing was related to ZFS-FUSE and also to the Lustre ZFS integration, both of which share most of the code (except for the ZPL which is only used in ZFS-FUSE). As part of this work I need to keep the code synchronized with OpenSolaris. I was in fact refactoring the rwlock functionality implemented on top of PThreads and ran into that issue, hence my question.
