nanosecond delay in kernel module

2006-08-15 Thread m . ehinger
Hi, what is the official way to delay in a kernel module for about 10 nanoseconds (1/1,000,000,000th second). I found DELAY(9), but it uses microseconds (1/1,000,000th second). Any help would be appeciated Maik ___ freebsd-hackers@freebsd.org

openospfd

2006-08-15 Thread David Gilbert
Is there anyone actively working on openospfd (the port)? There are systemic things like the fact they want to ignore lo0 destined routes (although I know how to patch that), but there are less obvious things that I havn't figured out. Like the fact that our version ignores if_tun and if_gre.

struct dirent question

2006-08-15 Thread Eric Anderson
Does the ifdef in the struct dirent (pasted in below) make any sense? Seems like regardless of whether the __BSD_VISIBLE is defined or not, the d_name length will always be 255 + 1. Eric struct dirent { __uint32_t d_fileno;/* file number of entry */ __uint16_t
