[PATCH] PCI: don't override drv->shutdown unconditionally

2005-06-17T19:34:20Z

There are many drivers that have been setting the generic driver model level shutdown callback, and pci thus must not override it. Without this patch we can have really bad data loss on various raid controllers. Signed-off-by: Greg Kroah-Hartman Signed-off-by: Linus Torvalds

When cfq I/O scheduler is selected, get_request() in __make_request() calls

2005-06-17T14:15:10Z

__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct cfq_queue) of the current process for the device and returns it. If it's not found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that get_request() fails) if no __GFP_WAIT flag. On the other hand, in __make_request(), get_request() is called without __GFP_WAIT flag at the first time. Thus, the get_request() fails when there is no existing queue, typically when it's called for the first I/O request of the process to the device. Though it will be followed by get_request_wait() for general case, __make_request() will just end the I/O with an error (EWOULDBLOCK) when the request was for read-ahead.

[PATCH] ALPS: fix enabling hardware tapping

2005-06-16T16:02:59Z

It looks like logic for enabling hardware tapping in ALPS driver was inverted and we enable it only if it was already enabled by BIOS or firmware. I have a confirmation from one user that the patch below fixes the problem for him and it might be beneficial if we could get it into 2.6.12.

[PATCH] sbp2 slab corruption fix

2005-06-16T16:02:59Z

This fixed a problem that showed up in the Fedora development tree a few weeks before the Fedora Core 4 release, initially as slab corruption, later as hard crashes on boot up, when slab debugging was disabled for the release. More details on the history at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424 The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a scsi_id, without explicitly requesting space for it. Since hostdata is declared as a zero-sized array, we don't get any such space by default, so it must be explicitly requested. The patch below implements just that.

This patch fixes q->unplug_thresh condition check in

2005-06-16T10:57:31Z

__elv_add_request(). rq.count[READ] + rq.count[WRITE] can increase more than one if another thread has allocated a request after the current request is allocated or in_flight could have changed resulting in larger-than-one change of nrq, thus breaking the threshold mechanism.
