Although RHEL 6 is based on the 2.6.32 kernel, for RHEL 6.1 the
argument list for sysfs callback functions follows the style of
kernel 2.6.35.

With the RHEL 7.0 kernel ib_register_mad_agent() takes eight
arguments. With the RHEL 7.1 kernel the same function takes nine
arguments. Detect at build time how many arguments this function
takes.

Code after BUG() is unreachable both with CONFIG_BUG=y and with
CONFIG_BUG=n. Hence remove such code. Detected by smatch.

* scst_lib: refuse WRITE SAME commands with UNMAP=0 and ANCHOR=1 or
with UNMAP=0 and no data buffer. SBC-4 requires to respond with
"ILLEGAL REQUEST / INVALID FIELD IN CDB" to such WRITE SAME commands.
* scst_lib: use the WRITE SAME(16) NODB bit to determine the data
buffer length.
* scst_vdisk: test for the ANCHOR bit via mask 0x10 instead of mask 0x01.
* scst_vdisk: print an error message if a WRITE SAME command has been
refused because of an unusual value of NUMBER OF LOGICAL BLOCKS.

This variable is no longer needed because devices are
removed from the devices list via list_del_init() before
being unregistered. See also trunk r5510 / commit f3820d5bc4.

Introduce a wait event and eliminate the msleep() call that is
used for waiting until an I/O context is ready.

Change the data type of iscsi_conn.read_iov into struct kvec * and
switch from iscsi_conn.read_size to iscsi_conn.read_msg.count for
kernel version 3.19 and later. Cast the return type of
get_zeroed_page() to void * since with this patch the read_iov
data type depends on the kernel version. Remove the (void __force
__user *) casts when assigning to iov_base since for a kvec iov_base
is a kernel pointer instead of a user space pointer. Switch to
iov_iter_kvec() to initialize conn->read_msg.msg_iter.

Rework the iSCSI target driver code such that it becomes easier
to port this code to kernel 3.19.

The put_page_callback patch only improves performance on single-socket
systems but not on systems with multiple CPU sockets. Hence do not
print a warning if the put_page_callback patch has not been applied.

The T10-PI patch (r6162) increases the time needed to run mkfs.ext4
over iSCSI from less than a second to several minutes. This is a
regression so revert the T10-PI patch until there is sufficient time
to find the root cause of this regression and to fix this regression.

This version is production used by SanDisk for quite some time and
passed all very hard internal tests. However, due to original qla2xxx
issues NPIV is not working in this version, so if you need NPIV either
use v3.0 of this driver or the driver from the QLogic git.
