[wplug-bsd] Patching a driver

[Brandon Kuczenski]

I'm working with samba at work and came across the following bug:

https://bugzilla.samba.org/show_bug.cgi?id=2794

in a somewhat unpleasant way.  It seems the samba people think that 
FreeBSD's ntfs driver is broken, and misreports the number of hard links 
for files on ntfs filesystems.

It looks like there is a simple one-line hack of a patch, to 
sys/fs/ntfs/ntfs_vnops.c, which is explained in the comments to the bug:

  before:
 	vap->va_nlink = ip->i_nlink;
  after:
 	vap->va_nlink = (ip->i_nlink ? ip->i_nlink : 1);

My question: what is the 'BSD' way to implement this patch and install the 
patched driver, if possible without rebuilding the kernel?

Thanks,
Brandon
