scsi: print single-character strings with seq_putc

2015-02-02T17:57:46+00:00

Using seq_putc to print a single character saves at least a strlen()
call and a memory access, and may also give a small .text reduction.

scsi: merge consecutive seq_puts calls

2015-02-02T17:57:45+00:00

Consecutive seq_puts calls with literal strings may be replaced by a
single call, saving a little .text.

scsi: replace seq_printf with seq_puts

2015-02-02T17:57:45+00:00

Using seq_printf to print a simple string is a lot more expensive than
it needs to be, since seq_puts exists. Replace seq_printf with
seq_puts when possible.

scsi: remove SPRINTF macro

2015-02-02T17:57:45+00:00

The macro SPRINTF doesn't save a lot of typing or make the code more
readable, and depending on a specific identifier (m) in the
surrounding scope is generally frowned upon. Nuke it.

scsi: use 64-bit value for 'max_luns'

2014-07-17T20:07:38+00:00

Now that we're using 64-bit LUNs internally we need to increase
the size of max_luns to 64 bits, too.

scsi: use 64-bit LUNs

2014-07-17T20:07:37+00:00

The SCSI standard defines 64-bit values for LUNs, and large arrays
employing large or hierarchical LUN numbers become more and more
common.

So update the linux SCSI stack to use 64-bit LUN numbers.

scsi: Remove CONFIG_SCSI_MULTI_LUN

2014-07-17T20:07:35+00:00

Obsolete; either use 'max_lun' if the host supports only a
limited number of LUNs or BLIST_NOLUN if the target has
problems addressing more than one LUN.

SCSI: remove unnecessary pci_set_drvdata()

2013-10-14T13:26:04+00:00

Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
