* | ide: ensure that we re-run the queue handlerJens Axboe2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | The conversion to blk_delay_queue() missed parts of IDE. Add a blk_delay_queue() to ensure that the request handler gets reinvoked when it needs to. Note that in all but one place the old plug re-run delay of 3 msecs is used, even though it probably could be shorter for performance reasons in some of those cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code has been converted over to the new explicit on-stack plugging, and delay users have been converted to use the new API for that.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert ->media_changed() to the new ->check_events() method. The conversion is mostly mechanical. The only notable change is that cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT. It used to return -EINVAL which would be treated as media changed. As media changer isn't supported anyway, this doesn't make any difference. This makes ide emit the standard disk events and allows kernel event polling. Currently, only MEDIA_CHANGE event is implemented. Adding support for EJECT_REQUEST shouldn't be difficult; however, given that ide driver is already deprecated, it probably is best to leave it alone.

* / kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* ide: clean up timed out request handlingTejun Heo2010-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8f6205cd572fece673da0255d74843680f67f879 introduced a bug where a timed out DMA request is never requeued and lost. 6072f7491f5ef391a575e18a1165e72a3eef1601 fixed this by making ide_dma_timeout_retry() requeue the request itself. While the fix is correct, it makes DMA and non-DMA paths asymmetric regarding how the in flight request is requeued. As long as hwif->rq is set, the IDE driver is assuming ownership of the request and the request should either be completed or requeued when clearing hwif->rq. In the timeout path, the ide driver holds onto the request as long as the recovery action (ie. reset) is in progress and clears it after the state machine is stopped (ide_stopped return), so the existing requeueing logic is correct. The bug occurred because ide_dma_timeout_retry() explicitly clears hwif->rq without requeueing it. ide_dma_timeout_retry() is called only by ide_timer_expiry() and returns ide_started only when ide_error() would return it - ie. after reset state machine has started in which case the state machine will eventually end up executing the ide_stopped path in ide_timer_expiry() after reset protocol is complete. So, there is no need to clear hwif->rq from ide_dma_timeout_retry(). ide_timer_expiry() will handle it the same way as PIO timeout path. Kill hwif->rq clearing and requeueing from ide_dma_timeout_retry() and let ide_timer_expiry() deal with it. The end result should remain the same. grepping shows ide_dma_timeout_retry() is the only site which clears hwif->rq without taking care of the request, so there shouldn't be similar fallouts.

The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window.

| * block: push down BKL into .open and .releaseArnd Bergmann2010-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.

| | | | | | | | | | | | | | | | | | | | ide_cd_error_cmd() can complete an erroneous request with leftover buffers. Signal this with its return value so that the request is not accessed after its completion in the irq handler and we oops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of io_req_t, drivers are now requested to fill out struct pcmcia_device *p_dev->resource[0,1] for up to two ioport ranges. After a call to pcmcia_request_io(), the ports found there are reserved, after calling pcmcia_request_configuration(), they may be used.
