kib 2008-09-12 09:53:29 UTC FreeBSD src repository Modified files: sys/i386/i386 sys_machdep.c vm_machdep.c sys/i386/include proc.h Log: SVN rev 182961 on 2008-09-12 09:53:29Z by kib When doing rfork(0), i.e. separating curproc VM from any other user of the same vmspace, decrement the reference count of the shared LDT instead of a newly-made copy. Code factually removed LDT from the process that did rfork(0). Introduce user_ldt_deref() function that does decrement of refcount for the struct proc_ldt, and call it in the rfork(0) case on the shared LDT.
