H A D | kern_linker.c | diff 43084 Sat Jan 23 01:45:22 MST 1999 peter Update userref handling after discussion with submitter of previous patch. lf can't be dereferenced after the unload attempt, in case it was freed. Instead, decrement first and back it out if the unload failed. This should be relatively immune to races caused by the user since the userref count will be zero for the duration of the actual unloading and will stop further kldunload attempts.
