Hello David Howells,
This is a semi-automatic email about new static checker warnings.
The patch 9549332df4ed: "fscache: Implement cache registration" from
Oct 20, 2021, leads to the following Smatch complaint:
fs/fscache/cache.c:186 fscache_put_cache()
warn: variable dereferenced before IS_ERR check 'cache' (see line 182)
fs/fscache/cache.c
181 {
182 unsigned int debug_id = cache->debug_id;
^^^^^^^^^^^^^^^
Dereferenced
183 bool zero;
184 int ref;
185
186 if (IS_ERR_OR_NULL(cache))
^^^^^
Checked too late.
187 return;
188
regards,
dan carpenter
