[PATCH] scsi_debug version 1.74
To check descriptor format sense data handling we need a source.
Clean up some other problems and improve support for st.
Changes:
- add 'dsense' option to generate descriptor sense data
format (default still fixed format)
- correct unit attention generation (only INQUIRY, REQUEST_SENSE
and REPORT_LUNS ignore it)
- better information sent to log in "noisy" mode (i.e. opts=1)
- correct and expand standard INQUIRY response, include version
descriptors
- filter MODE_SENSE command so that subpage!=0 generates error
- add REWIND (SSC) command support (NOP)

[PATCH] Add BLIST_INQUIRY_36 to all USB blacklist entries
This patch adds the BLIST_INQUIRY_36 flag to all the SCSI blacklist
entries for USB devices. While it may not be strictly necessary for all
of them, it doesn't hurt: Since the usb-storage driver doesn't use any of
the INQUIRY data after the first 36 bytes, there's no reason to try
reading any more of it. And some devices crash when we try to read more,
even though they advertise that more bytes are available. The usb-storage
driver does try to set the flag automatically, but the blacklist entries
override that setting.

New version of the NETIF_F_LLTX for network devices patch.
This allows network drivers to set the NETIF_F_LLTX flag
and then do their own locking in start_queue_xmit.
This lowers locking overhead in this critical path.
The drivers can use try lock if they want and return -1
when the lock wasn't grabbed. In this case the packet
will be requeued. For better compatibility this is only
done for drivers with LLTX set, others don't give a special
meaning to -1.
Most of the modern drivers who have a lock around hard_start_xmit
can just set this flag. It may be a good idea to convert the spin
lock there to a try lock. The only thing that should be audited
is that they do enough locking in the set_multicast_list function
too, and not also rely on xmit_lock here.
Now doesn't move any code around and does things with gotos instead.
The loop printk is also still there even for NETIF_F_LLTX
For drivers that don't set the new flag nothing changes.

[PATCH] fbdev: Clean up framebuffer initialization
This patch probably deserves discussion among developers.
Currently, the framebuffer system is initialized in a roundabout manner.
First, drivers/char/mem.c calls fbmem_init(). fbmem_init() will then
iterate over an array of individual drivers' xxxfb_init(), then each driver
registers its presence back to fbmem. During console_init(),
drivers/char/vt.c will call fb_console_init(). fbcon will check for
registered drivers, and if any are present, will call take_over_console()
in drivers/char/vt.c.
This patch changes the initialization sequence so it proceeds in this
manner: Each driver has its own module_init(). Each driver calls
register_framebuffer() in fbmem.c. fbmem.c will then notify fbcon of the
driver registration. Upon notification, fbcon calls take_over_console() in
vt.c.
The following are the changes brought about by this patch:
- Each subsystem (fbcon, fbmem, xxxfb) will have their own module_init.
Thus, explicit calls to each subsystem's init functions are eliminated.
- The struct fb_drivers array in fbmem.c can be removed. This slashes
around 400 lines in fbmem.c
- Parsing of kernel boot options were done by fbmem.c calling each
driver's xxxfb_setup() function. Because this is not possible with this
patch, drivers can choose to either:
- have their own __setup() routine
- call fb_get_options("xxxfb") and pass the return value to
xxxfb_setup(). This is to maintain compatibility with the
'video=xxxfb:<options>' semantics.
- Getting a framebuffer console will occur a bit late during the boot
process since the initialization sequence will depend upon the link
order. So, 'video/' is moved up in drivers/Makefile, shortly after
'pci/'
- Because driver initialization will be dependent on the link order,
hardware that depends on other subsystems (agpgart, usb, serial, etc) may
choose to initialize after the subsystems they depend on.
[PATCH] fbcon: take over console on driver registration
- This fixes another regression from 2.4. If fbcon is compiled
statically, and the framebuffer driver is compiled as a module, doing a
'modprobe xxxfb' does nothing to the console. This has generated
numerous bug reports from users.
With this patch, fbmem will notify fbcon upon driver registration
allowing fbcon to take over the console.
- This also fixes con2fbmap not working if fbcon is compiled as a module
using the same mechanism as described above.
This patch speeds up scrolling of tdfxfb by maximizing var->yres_virtual so
tdfxfb uses SCROLL_PAN_MOVE instead of SCROLL_REDRAW. This is true whether
CONFIG_FB_3DFX_ACCEL is set or not. This problem was reported by Paolo
Ornati <ornati@fastwebnet.it> who also made substantial contributions to
solve this problem.
This patch also fixes compile errors when CONFIG_FB_3DFX_ACCEL is false.
