a1f9d8d23f [PATCH] v9fs: replace strlen on newly allocated by __getname buffers to PATH_MAX
v9fs_vfs_readlink allocates space for the link using __getname and
errorneously uses strlen on the newly allocated buffer to check if the buffer
passed by the user is bigger than the one returned by __getname.

The patch replaces the strlen usage to PATH_MAX, which is the actual size of
the buffers returned by __getname.

b501611a6f [PATCH] v9fs: readlink extended mode check
LANL reported some issues with random crashes during mount of legacy protocol
servers (9P2000 versus 9P2000.u) -- crash was always happening in readlink
(which should never happen in legacy mode).  Added some sanity conditionals to
the get_inode code which should prevent the errors LANL was seeing.  Code
tested benign through regression.
