Hello Bart Van Assche,
This is a semi-automatic email about new static checker warnings.
The patch 5cadafb236df: "target/cxgbit: Fix endianness annotations"
from Jan 13, 2017, leads to the following Smatch complaint:
drivers/target/iscsi/cxgbit/cxgbit_cm.c:1836 cxgbit_fw4_ack()
warn: variable dereferenced before check 'p' (see line 1834)
drivers/target/iscsi/cxgbit/cxgbit_cm.c
1833 struct sk_buff *p = cxgbit_sock_peek_wr(csk);
1834 const u32 csum = (__force u32)p->csum;
^^^^^^^
We moved this dereference earlier
1835
1836 if (unlikely(!p)) {
^
so now it's before the NULL check
1837 pr_err("csk 0x%p,%u, cr %u,%u+%u, empty.\n",
1838 csk, csk->tid, credits,
regards,
dan carpenter
