Most of those that did managed to hit problems with apps that did writes via mmap. So, I added a page_mkwrite call and worked out cow safe mmap writes. Terje R?sten sent along a btrfsprogs patch so that it compiles properly on FC7 (thanks!). I'll have a site up on oss.oracle.com/projects with mailing lists and links to my HG trees shortly. Until then: http://oss.oracle.com/~mason/btrfs/ has the latest tar balls. -chris - 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/
