This has minor usbcore cleanups: DOC: - the changes passing a usb_interface to driver probe() and disconnect() weren't reflected in their adjacent docs. likewise they still said it was possible to get a null usb_device_id (no more). - the (root) hub API restrictions from rmk's ARM patch weren't flagged - mention the non-dma-coherent cache issue for usb_buffer_alloc() - mention disconnect() cleanup issue with usb_{control,bulk}_msg() [ you can't cancel those urbs from disconnect() ] CODE - make driver ioctl() use 'usb_interface' too ... this update also resolves an old 'one instance per device' bad assumption - module locking on driver->ioctl() was goofy, kept BKL way too long and didn't try_inc_mod_count() like the rest of usbcore - hcd unlink code treated iso inappropriately like interrupt; only interrupt still wants that automagic mode - move iso init out of ohci into shared submit_urb logic - remove interrupt transfer length restriction; hcds that don't handle packetization (just like bulk :) should be updated, but device drivers won't care for now.

/sbin/hotplug is now called when any device is added or removed from the system.

QDIO_BH was never actually used anyway, and won't do much good now BHs are gone.

Beginning of proper refcounting. New helpers introduced, several drivers switched to using them for dynamic allocation of gendisks. Once everything is switched (and that will be way easier than per-drive gendisks series) we will be able to add sane reference counts on gendisk, at which point we can safely put pointer to gendisk in struct block_device / struct request and we had pretty much won - from that point it's pretty straightforward crapectomy in drivers.

char *major_name replaced with char disk_name[16]; All uses of ->major_name replaced with those of ->disk_name and (obviously) simplified big way. Bunch of arrays, kmallocs, etc. is gone.

... now it can be done. We also drop almost all arguments - there is only one caller and everything is determined by the first argument.

Cleans the handling of partitioning up. More or less the same story as with other drivers...

Alexander Viro authored
corrected handling of sizes. Ugh.

get_gendisk() now takes dev_t (instead of kdev_t) and gets an additional argument - int *part. Set to 0 for non-partitioned, partition number for partititoned. Callers updated. Yes, I hate passing return values that way ;-/ We need that since old "minor(dev) - disk->first_minor" doesn't work for stuff with non-trivial numbers (e.g. floppy) and get_gendisk() really has to return both gendisk and partition number. Fortunately, amount of callers of gendisk() is about to drop RSN big way...

The list used to generate /proc/partitions turned into list_head one; we also restore the old order of elements (originally we added to the end of list; recent changes had reverted that, now we are back to original order).

Just for niceness, loop should clear queue queuedata when it exits.
-
Jens Axboe authored
These days we only require a clear of BIO_UPTODATE on -EIO, we don't set it on success. This breaks raid5. It appears to clear BIO_UPTODATE fine but doesn't start out with it set.

This makes loop honor the queue restrictions by basically stacking all of those, and mirroring the merge_bvec_fn() on the target queue. It also switches loop to use per-loop device queues, since that is the only sane way to do this from a performance POV. Also, in principle I find it to be much nicer if every distinct block device has its own queue.
-
Jens Axboe authored
There's really no reason to BUG() out on a bio that is too big, the gentleman thing to do would be to print a warning and just end the bio with -EIO quietly.
-
Jens Axboe authored
Add a function to set queue merge_bvec_fn to mimic the rest of the api, and also add documentation for that and blk_queue_prep_rq().

The might_sleep() thing caught ide, which calls request_irq() with a lock held. It can be argued that this is a bad thing, however I think it can also validly be argued that requesting an irq should not be a blocking operation. This might even remove some driver bugs where usage count is not incremented during init... It can also be argued, that the very first irq requests cannot be blocking for io anyways, for good reason :-)

This fixes a procfs crash noticed by Anton Blanchard. The procfs code can have a reference even to an already exited task, so it needs to follow special rules accessing p->sig. The atomic-signals patch made this bug happen at a much higher frequency, but procfs i believe was buggy ever since, it potentially used the freed signal structure - which just did not result in a crash like it does today. The proper fix is to take the tasklist read-lock in collect_sigign_sigcatch(), this excludes __exit_sighand() freeing the signal structure prematurely.
