Be aware that how BK does I/O is with write() on the way out but with mmap on the way in. The process which forked renumber has just written the file and the renumber process is reading it with mmap.
If there are still any problems with mixing read/write and mmap then that may be a prolem but I would have expected to see things start going wrong on a page boundary and the one core dump I saw was page aligned at the tail but not at the head, it started in the middle of the page.
I've told my team to drop this unless someone can show that it happens on other kernels, this smells like a kernel bug to me, if it were a BK bug we should have been getting hundreds of complaints by now. We can jump back on it if need be, let us know if you think it is a BK problem after all. -- --- Larry McVoy lm at bitmover.com http://www.bitkeeper.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
