* [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern2005-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."

* [PATCH] USB: ub 4: Zaitcev's quasi-S/GPete Zaitcev2005-09-08
| | | | | | | | | | | | | | | | Back out Axboe-style quasi-S/G and replace it with one command and repeated URBs. This is similar to what usb-storage does, only instead of a few URBs allocated together, one URB is reused. Jens's idea was very nice, but it collapsed when I had to support packet commads for CD burning. I cannot issue two or more packet commands where application expected only one. However, burning does not work completely yet. The cdrecord starts, recognizes the device, then aborts without writing a TOC.

* [PATCH] USB: ub 1/3: Axboe's quasi-S/GPete Zaitcev2005-09-08
| | | | | | | | | | | | | | | | | | | | This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and implemented that night before 4 a.m. Surprisingly, it worked right away... Alas, I had to skip some OLS partying, but it was for the good cause. Now the speed of ub is quite acceptable even on partitions with small block size. The ub does not really support S/G. Instead, it just tells the block layer that it does. Then, most of the time, the block layer merges requests and passes single-segmnent requests down to ub; everything works as before. Very rarely ub gets an unmerged S/G request. In such case, it issues several commands to the device. I added a small array of counters to monitor the merging (sg_stat). This may be dropped later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I ran across a memory leak related to the cfq scheduler. The cfq init function increments the refcnt of the associated request_queue. This refcount gets decremented in cfq's exit function. Since blk_cleanup_queue only calls the elevator exit function when its refcnt goes to zero, the request_q never gets cleaned up. It didn't look like other io schedulers were incrementing this refcnt, so I removed the refcnt increment and it fixed the memory leak for me. To reproduce the problem, simply use cfq and use the scsi_host scan sysfs attribute to scan "- - -" repeatedly on a scsi host and watch the memory vanish.

The original resize implementation was incorrect in the following points. * actual allocation size of tag_index was shorter than real_max_size, but assumed to be of the same size, possibly causing memory access beyond the allocated area. * bits in tag_map between max_deptn and real_max_depth were initialized to 1's, making the tags permanently reserved. In an attempt to fix above two bugs, I had removed allocation optimization in init_tag_map and real_max_size. Tag map/index were allocated and freed immediately during resize. Unfortunately, I wasn't considering that tag map/index can be resized dynamically with tags beyond new_depth active. This led to accessing freed area after shrinking tags and led to the following bug reporting thread on linux-scsi. http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2 To fix the problem, I've revived real_max_depth without allocation optimization in init_tag_map, and Andrew Vasquez confirmed that the problem was fixed. As Jens is not going to be available for a week, he asked me to make sure that this patch reaches you. http://marc.theaimsgroup.com/?l=linux-scsi&m=112325778530886&w=2 Also, a comment was added to make sure that real_max_size is needed for dynamic shrinking.

Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the block layer now, so let's save atomic memory for things like networking.

* | [PATCH] ll_rw_blk: prevent huge request allocationsJens Axboe2005-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we cap request allocations at q->nr_requests, but we allow a batching io context to allocate up to 32 more (default setting). This can flood the queue with request allocations, with only a few batching processes. The real fix would be to limit the number of batchers, but as that isn't currently tracked, I suggest we just cap the maximum number of allocated requests to eg 50% over the limit. This was observed in real life, users typically see this as vmstat bo numbers going off the wall with seconds of no queueing afterwards. Behaviour this bursty is not beneficial.

I am removing the partition info from the CCISS_GETLUNINFO ioctl as I was informed my "driver had no damn business reading that structure." ;) The application folks are to use /proc or /sys for partition info from now on. I am only aware of a few apps that use this ioctl and I'm not sure they ever used the partition info.

* | [PATCH] cciss: pci domain info pass 2Mike Miller2005-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This is pass 2 of my patch to add pci domain info to an existing ioctl. This time I insert the domain between dev_fn and board_id as Willy suggested and change the var to unsigned short to ease Christoph's concerns. Although I thought unsigned int was the correct var type for this. I also thought it didn't matter where I inserted it in the structure.

* | [PATCH] cciss: pci id fixMike Miller2005-06-27
| | | | | | | | | | | | | | | | | | | | | | This patch fixes a PCI ID I got wrong before. It also adds support for another new SAS controller due out this summer. I didn't have a marketing name prior to my last submission. Also modifies the copyright date range.
