Add __must_hold() attribute to zfcp_qdio_sbal_get() in order to let clang's context analysis know that qdio->req_q_wq must be held on function entry. This is also documented above the function. Without this annotation this leads to a valid warning when context analysis is enabled: drivers/s390/scsi/zfcp_qdio.c:287:8: warning: expecting spinlock '->req_q_lock' to be held at start of each loop [-Wthread-safety-analysis] 287 | ret = wait_event_interruptible_lock_irq_timeout(qdio->req_q_wq, | ^ Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Link: https://patch.msgid.link/20260806134759.2122369-2-hca@linux.ibm.com Signed-off-by: Martin K.
