I'm also trying to deal with setting arbitrary dev_t values in buf_t objects, accessing the try variants and determining the current state of read-write locks, getting a device switch table entry from a major number, interrupting threads sleeping on sockets, timeout/untimeout, thread_abort_safely, ... and that's just the platform support code. Who knows what vfs, vnode lifetime, lookup, mmap and UBC issues still await! I've been porting our Network FS to tiger for the past two months and have run into my own set of KPI deficiencies with the socket KPI and the locking KPI (those try variants need to be exposed and R/W lock state too). I've opened Radars and talked with Josh at WWDC, but just wanted to reinforce Sam's experiences with what the KPI lacks. I've not run into any real problems with the VFS KPI, and we don't use buf_t's so I can't comment on that interface. Finally, I want to say thanks to Josh and everyone else from Apple for the replies to this list, they are very helpful. This email sent to site_archiver@lists.apple.com
