Getting vnode + credentials of a file from a struct mount and UFS inode #

[Jonathan Stuart]

Hi Matthew,

Thanks, I'll give it a shot.. for some reason f_cred off the vnode is returning all zeros for uid/gid, and
pulling the VTOI does the same thing (using getvnode()).. do these not get initialized properly?

Ciao,
Jonathan

VFS_VGET(mp, ino, flags, &vp) is probably what you want.
