b391277a56 sd, sr: fix Driver 'sd' needs updating message
If a SCSI ULD driver sets blk_queue_prep_rq(), it should clean it
up itself on remove(), and not from the bus callbacks. This
removes the need to hook into bus->remove(), which should not
be used at the same time as driver->remove().

017b2ae33c ibmvfc: Fix endless PRLI loop in discovery
Fixes a problem seen where sending a PRLI to a target
resulted in it sending a LOGO. This caused the ibmvfc
driver to go back through discovery again, which caused
another PRLI attempt, which caused another LOGO. Fix this
behavior by ignoring LOGO if we haven't even logged into
the target yet.

7414705ea4 libfc: Add runtime debugging with debug_logging module parameter
This patch adds the /sys/module/libfc/parameters/debug_logging
file to sysfs as a module parameter. It accepts an integer
bitmask for logging. Currently it supports:

   bit
LSB 0 = general libfc debugging
    1 = lport debugging
    2 = disc debugging
    3 = rport debugging
    4 = fcp debugging
    5 = EM debugging
    6 = exch/seq debugging
    7 = scsi logging (mostly error handling)

the other bits are not used at this time.

The patch converts all of the libfc source files to use
these new macros and removes the old FC_DBG macro.

a9e0edb687 scsi_transport_spi: Blacklist Ultrium-3 tape for IU transfers
There have been several bug reports which identified the Ultrium-3
tape as just hanging up on the bus during certain types of IU
transfer.  The identified culpret is type 0x02 (MULTIPLE COMMAND)
transfers.  The only way to prevent this tape wedging is to prevent it
from using IU transfers at all.  So this patch uses the exported
blacklist matching technology to recognise the drive and force it not
to use IU transfers.

598fa4b775 enhance device info matching for multiple tables
The current scsi_devinfo.c matching routines use a single table for
the global blacklist.  However, we're developing a need to blacklist
from specific transports too (notably some tape drives using SPI which
don't respond well to high speed protocols).  Instead of developing
separate blacklist matching for each transport class needing it,
enhance the current list matching to permit multiple lists.

32382492eb iscsi_tcp: propogate EAGAIN from sendpage to libiscsi
The net layer might return -EAGAIN because it could not
get space/mem within the sock sndtimeo or becuase the tcp/ip
connection was down. For the latter we do not want to retry
because the conn/session should just be shutdown and restarted.
libiscsi knows the state of the session recovery so propogate
this error to that layer. It will either do iscsi recovery
or have us retry the operation. Right now if we have partially
sent a pdu we would always retry the IO xmit slowing down
recovery.

Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"

./Documentation/tracers/ftrace.txt file.

And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
existed in kernel source like ftrace, DRM, Wireless, Documentation,
Network[sky2]files to mount debugfs filesystem.

debugfs means debug filesystem for debugging easy to use by greg kroah
hartman. "/sys/kernel/debug/" name is suitable as directory name
of debugfs filesystem.

43fac4d97a [SCSI] qla2xxx: Resolve a performance issue in interrupt
