| * Revert revert of "[SCSI] fix usb storage oops"Linus Torvalds2005-12-121-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 1b0997f561bf46689cc6e0903f342e9bf2506bf1, which in turn reverted 34ea80ec6a02ad02e6b9c75c478c18e5880d6713 (which is thus re-instated). Quoth James Bottomley: "All it's doing is deferring the device_put() from the scsi_put_command() to after the scsi_run_queue(), which doesn't fix the sleep while atomic problem of the device release method. In both cases we still get the semaphore in atomic context problem which is caused by scsi_reap_target() doing a device_del(), which I assumed (wrongly) was valid from atomic context." who also promised to fix scsi_reap_target().

| * [PATCH] md: use correct size of raid5 stripe cache when measuring how full it isNeilBrown2005-12-121-3/+4
| | | | | | | | | | | | | | | | | | | | | | The raid5 stripe cache was recently changed from fixed size (NR_STRIPES) to variable size (conf->max_nr_stripes). However there are two places that still use the constant and as a result, reducing the size of the stripe cache can result in a deadlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this..

| * [PATCH] Add timestamp field to process eventsMatt Helsley2005-12-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a timestamp field to the events sent via the process event connector. The timestamp allows listeners to accurately account the duration(s) between a process' events and offers strong means with which to determine the order of events with respect to a given task while also avoiding the addition of per-task data. This alters the size and layout of the event structure and hence would break compatibility if process events connector as it stands in 2.6.15-rc2 were released as a mainline kernel.

More change is needed here: sg claims to dirty even pages written from, and st claims not to dirty even pages read into; and SetPageDirty is not adequate for this nowadays.

But that's irrelevant to your pain, except... One extract from the patches I'd like to send Doug and Kai for 2.6.15 or 2.6.16 is this below: since the incomplete get_user_pages path omits to reset res, but has already released all the pages, it will result in premature freeing of user pages, and behaviour just like you've seen. Though I'd have thought incomplete get_user_pages was an exceptional case, and a bit surprised you'd encounter it. Perhaps there's some other premature freeing in the driver, and this instance has nothing whatever to do with it. If the problem were easily reproducible, it'd be great if you could try this patch; but I think you've said it's not :-( Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
