I'm having a hard time figuring out what this sentence has to do with

As proposed by the SRP (draft) standard, ib_srp reserves one ring element for
SRP_TSK_MGMT requests. This patch makes sure that the SCSI mid-layer never
tries to queue more than (SRP request limit) - 1 SCSI commands to ib_srp. This
improves performance for targets whose request limit is less than o
Implements SRP_CRED_REQ and SRP_AER_REQ, which are information units defined
in the SRP (draft) standard. Adds declarations for the SRP_CRED_REQ,
SRP_CRED_RSP, SRP_AER_REQ and SRP_AER_RSP information units to

The information unit transmit ring (srp_target.tx_ring) in ib_srp is currently
only used for allocating requests sent by the initiator to the target. This

This series of three patches adds SRP_CRED_REQ ans SRP_AER_REQ support in
ib_srp. Both are information units defined in the SRP (draft) standard.
Changes in v5 compared to v4:
- Added support for processing the SRP_AER_REQ information unit.
- Introduced a new symbolic name, SRP_NORMAL_REQ_SQ_SIZE,

This code initializes ret to -ENOMEM, but actually ret is not used in the
code starting at err7, and -ENOMEM is always returned in this case, so the
initialization of ret is unnecessary.
The semantic match that finds this problem is as follows:

I see, looks like iwcm.c accounts for most of the BUG* calls made from the
core, could be nice
to reduce them over time.
