Negative constant left-shift is undefined behaviour in the C standard,
and as such newer versions of clang (at least) warn against it. GCC
supports it for a long time, but it would be better to remove it and
rely on defined behaviour.
My understanding is "~(-1 << N)" in 2's complement is intended

In "XFS over network block device" scenario XFS can create IO requests
with slab-based XFS metadata. During processing such requests
tcp_sendpage() can merge skb fragments with neighbour slab objects.
If receiving side is located on the same host tcp_recvmsg() can trigger
BUG_ON in hardening check
T6 adapters generates DDP completion message on receiving
all iSCSI pdus in a sequence, because of this driver
can not keep track of tcp sequence number for T6 adapters.

Instead of using viid to get pf number, directly get pf
number from lldi->pf.

During expander reset handling, the driver invokes kernel function
scsi_host_find_tag() to obtain outstanding requests associated with
the scsi host managed by the driver. Kernel’s block layer may return
stale entry for one or more outstanding requests if blk-mq is enabled.
This may lead to Kernel

We had a test-report where, under memory pressure, adding LUNs to the
systems would fail (the tests add LUNs strictly in sequence):

Noticed during editing that vim would remove some trailing spaces.

Hi,
I've encountered frequent command timeout while doing heavy pressure of small

using HGST SAS disks. HBA setup dmesg reports it has NCQ capability. By google
