Changing a lun's queue depth (/sys/block/sdX/device/queue_depth) isn't sticky when the device is connected via a QLogic fibre channel adapter. The QLogic qla2xxx fibre channel driver dynamically adjusts a lun's queue depth. If a user has a specific need to limit the number of commands issued to a lun (say a tape drive, or a shared raid where the total commands issued to all luns is limited at the controller level, for example) and writes a limiting value to /sys/block/sdXX/device/queue_depth, the qla2xxx driver will silently and gradually increase the queue depth back to the driver limit of ql2xmaxqdepth. While reducing this value (module parameter) or increasing the interval between ramp ups (ql2xqfullrampup) offers the potential for a work around it would be better to have the option of just disabling the dynamic adjustment of queue depth. This patch implements an "off switch" as a module parameter.

Set the module parameter ql2xmultique_tag to 1 to enable this feature. In this mode, the total number of response queues created is equal to the number of online cpus. Turning the block layer's rq_affinity mode on enables requests to be routed to the proper cpu and at the same time it enables completion of the IO in a response queue that is affined to the cpu in the request path.

The short-circuit to skip the non-applicable 'full-login-lip' process on 81xx ISPs was nested too deeply in the 'bus-reset' routine, as the code in qla2x00_loop_reset() should skip the whole enable_lip_full_login process. The original code could cause device tear-down due to the qla2x00_wait_for_loop_ready() call taking a large amount of time.

Martin Knoblauch reports that trying to build 2.6.30-rc6-git3 with RHEL4.3 userspace (gcc (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)) causes an internal compiler error (ICE): drivers/char/random.c: In function `get_random_int': drivers/char/random.c:1672: error: unrecognizable insn: (insn 202 148 150 0 /scratch/build/linux-2.6.30-rc6-git3/arch/x86/include/asm/tsc.h:23 (set (reg:SI 0 ax [91]) (subreg:SI (plus:DI (plus:DI (reg:DI 0 ax [88]) (subreg:DI (reg:SI 6 bp) 0)) (const_int -4 [0xfffffffffffffffc])) 0)) -1 (nil) (nil)) drivers/char/random.c:1672: internal compiler error: in extract_insn, at recog.c:2083 and after some debugging it turns out that it's due to the code trying to figure out the rough value of the current stack pointer by taking an address of an uninitialized variable and casting that to an integer. This is clearly a compiler bug, but it's not worth fighting - while the current stack kernel pointer might be somewhat hard to predict in user space, it's also not generally going to change for a lot of the call chains for a particular process. So just drop it, and mumble some incoherent curses at the compiler.

Commit c45d6320 ("fix reference counting of ftdi_private") stopped ftdi_sio_port_remove() from directly freeing the port-private data, with the intention if the port was still open, it would be freed when ftdi_close() is eventually called and releases the last refcount on the structure. That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close(). Remove a bogus comment too, while we're at it. And stop doing things inside "if (priv)" -- it must _always_ be there. Based loosely on an earlier patch by Daniel Mack, and suggestions by Alan Stern.

After upgrading my distcc boxes from gcc 4.2.2 to 4.4.0, the function graph tracer broke. This was discovered on my x86 boxes. The issue is that gcc used the same register for an output as it did for an input in an asm statement. I first thought this was a bug in gcc and reported it. I was notified that gcc was correct and that the output had to be flagged as an "early clobber". I noticed that powerpc had the same issue and this patch fixes it.
