Because of the new UFS2 birth time attribute, I have to call utimes() before setattr(). Struct stat has no member for the file birth time. Any suggestions to improve setattr() in respect of the new UFS2. The systime of 5.0 restore decreases around 9%. from man utimes For filesystems that support file birth (creation) times (such as UFS2) the birth time will be set to the value of the second element if the second element is older than the currently set birth time. To set both a birth time and a modification time, two calls are required; the first to set the birth time and the second to set the (presumably newer) modification time. Ideally a new system call will be added that allows the setting of all three times at once. I'm also willing to implement the proposed new syscall, any suggestions for name and type of arguments (probably an array of struct timespec). The kernel code already supports an array with all three time stamps.
