Yeah, the topic says "minor", but the key is "lots". I believe I have fixed a moderate number of minor bugs in the POSIX fifo code (fifofs). This was a result of writing a set of regression tests before trying to fix a serious race condition in fifofs, as I was afraid I would break fifofs subtly in the process. The result was finding lots of bugs instead, which are now believed to be fixed, and the regression test suite runs to completion without errors. However, this doesn't mean I haven't broken something, as the semantics of fifos are (at best) tricky. If you use applications that use fifos, please test them on a recent kernel from the CVS HEAD. I plan to merge many if not all of these changes to RELENG_6 in the immediate future, and RELENG_5 a bit after that. I'd much rather hear about bugs sooner rather than later. Thanks, Robert N M Watson
