vnodes and hard links
I am confused about what vnode operation vop_lookup_desc should return for two
directory entries that refer to the same underling filesystem inode (i.e. hard
// VNODE(9): There is a unique vnode allocated for each active file,
directory, mounted-on file, fifo, domain socket, symbolic link and device."
Does this mean that (1) a unique vnode per directory entry or (2) a unique
vnode per inode ?
I suspect that the answer is (2), but when I do this and just return the
already locked vnode, I get this assertion.
// Reader / writer lock error: rw_vector_exit: assertion failed:
RW_COUNT(rw) != 0
Examples from other filesystems in the code base either do the same or perform
a vget() based some flags, but if the vnode is active it would not be on the
