Hi Andriy and Alexander, Firstly, let me introduce myself;) I'm a graduate student from Shanghai, timezone: GMT+8. I began to use FreeBSD and programing under it from 2009. 5 years experience in *nix posix C programing and 2 years experience in linux kernel programing. I have some experience in linux udf filesystem during one intern job -- add read_12 support which is similar as http://msdn.microsoft.com/en-us/library/windows/hardware/gg441227%28v=vs.85%29.aspx, but in an ugly hack way ;) and some hacks to improve the read performance. I want to take "Port NetBSD's UDF implementation (GSoC)" as my gsoc2012 project. Have anyone taken it?seems no according david_chi on freebsd-soc? I did some homework about this project: 1. the udf was implemeted in FreeBSD firstly then ported to NetBSD, the supported revisions is old. Then Reinoud Zandijk implemented most of UDF features and write support win latest udf revision in mind. 2. The work includes kernel (sys/fs/udf) source code and userland mount_udf. And can be completed by either sync the FreeBSD's implementation with NetBSD's or port NetBSD's from scratch. I like the second method. Any suggestions? 3. The difficulty of this project is how to resolve the lock, vm and vfs subsystem difference between NetBSD and FreeBSD. Would you please give some suggestions about it? Thanks in advance, Yongcong _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
