Hi all,

After merging the cifs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from fs/cifs/dns_resolve.c:18:
fs/cifs/cifsglob.h: In function 'cifs_get_tlink':
fs/cifs/cifsglob.h:1169:14: error: passing argument 1 of 'atomic_inc' from incompatible pointer type [-Werror=incompatible-pointer-types]
1169 | atomic_inc(&tlink->tl_count);
| ^~~~~~~~~~~~~~~~

| refcount_t * {aka struct refcount_struct *}

179 | atomic_inc(atomic_t *v)
| ~~~~~~~~~~^

and lots more similar ...

Caused by commit

ef242296e441 ("fs:cifs: convert from atomic_t to refcount_t on tlink->tl_count")

Please write, review, test (repeat) and, only then, publish. :-(

I have used the cifs tree from next-20211115 for today.
