dillon 2005/03/03 22:10:09 PST DragonFly src repository Modified files: sys/kern kern_msfbuf.c Log: msf_buf_alloc() can be called with a NULL vm_page_t when e.g. the first page cannot be easily located, typically due to a user buffer which is not faulted in. Fix a NULL pointer dereference panic that occurs in that case.
