Linus Torvalds 6767157e30 9p: fix slab cache name creation for real 
commit a360f311f57a36e96d88fa8086b749159714dcd2 upstream.

This was attempted by using the dev_name in the slab cache name, but as
Omar Sandoval pointed out, that can be an arbitrary string, eg something
like "/dev/root".  Which in turn trips verify_dirent_name(), which fails
if a filename contains a slash.

So just make it use a sequence counter, and make it an atomic_t to avoid
any possible races or locking issues.
