Yes, to clarify - I changed the code to be fallocate(fd, 0, 0, 4); and then posix_fallocate(fd, 0, 4); (which is the same I guess) and tried it on different filesystems, and on btrfs I ended up with entire block (of zeroes). If it's fixed in latest tree it's fine, I guess that fix isn't in fedora's 2.6.32.3 -- This message represents the official view of the voices in my head -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
