Hello Herbert Xu,
This is a semi-automatic email about new static checker warnings.
The patch 40137906c5f5: "rhashtable: Add nested tables" from Feb 11,
2017, leads to the following Smatch complaint:
lib/rhashtable.c:149 bucket_table_free()
warn: variable dereferenced before check 'tbl' (see line 146)
lib/rhashtable.c
145 {
146 if (tbl->nest)
^^^^^^^^^
New unchecked dereference.
147 nested_bucket_table_free(tbl);
148
149 if (tbl)
^^^
Old code checked for NULL.
150 kvfree(tbl->locks);
151
regards,
dan carpenter
