VOP_CREATE hanging

[Adam Burkepile <sadpoti%gmail.com@localhost>]

For my subfile project I am creating a directory and not attaching it  
to a parent directory, but rather storing the inode number of the  
directory and retrieving it using VGET. I'm having a problem when I  
try to create files within this directory however, it seems to just  
hang. Seems to be when I call VOP_CREATE so I was thinking I might  
have some argument messed up but I've been at it for awhile and can't  
seem to find the problem.

Here is a snipit of code from when I attempt to create the file:

                printf("subfile not found, needs to be created\n");
                NDINIT(&sfnd, CREATE, TRYEMULROOT, UIO_USERSPACE,
                        SCARG(uap, sub_path));

                sfnd.ni_cnd.cn_nameiop = CREATE;
                sfnd.ni_cnd.cn_flags |= LOCKPARENT | LOCKLEAF;
                if ((SCARG(uap, flags) & O_EXCL) == 0 && ((SCARG(uap,  
flags) & O_NOFOLLOW) == 0))
                        sfnd.ni_cnd.cn_flags |= FOLLOW;

                /* lock subfile directory */
                if(VOP_ISLOCKED(sdvp) == 0){
                        printf("sdvp is unlocked, now locking\n");
                        vn_lock(sdvp, LK_EXCLUSIVE | LK_RETRY);
                }

                /* set the attr of the new file */
                VATTR_NULL(&sfva);
                sfva.va_type = VREG;
                sfva.va_mode = ((bva.va_mode &~ cwdi->cwdi_cmask) &  
ALLPERMS) &~ S_ISTXT;
                if (SCARG(uap, flags) & O_EXCL)
                        sfva.va_vaflags |= VA_EXCLUSIVE;

                error = VOP_CREATE(sdvp,&sfvp,&(sfnd.ni_cnd),&sfva);
                printf("VOP_CREATE error = %d\n",error);

Any advice on why it is hanging or even why it might be hanging this  
would be greatly appreciated. I can post more info if that would help.
