block: floppy: fix rmmod lockup

2008-03-13T20:11:43+00:00

Floppy rmmod locks up when no such hardware was initialized, since there is
nobody to wake the remove code up.  Remove the completion, because release is
called during platform_unregister anyway.

blk_end_request: changing floppy (take 4)

2008-01-28T09:36:21+00:00

This patch converts floppy to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.

As a result, the interface of internal function, floppy_end_request(),
is changed.

floppy: remove register keyword use from floppy driver

2007-10-17T15:43:03+00:00

The floppy drive is slow.  These days I see absolutely no good reason why the
floppy driver should try to gain a tiny bit of speed by telling gcc to
optimize access to some variables via the register keyword.  Better to just
leave gcc free to do whatever optimizations it deduces to be sane and not
hamper it by telling it that some variables in the floppy driver are special
and need to be fast (they don't).

floppy: remove dead/commented out code from floppy driver

2007-10-17T15:43:03+00:00

A good initial step for a cleanup seems to me to be getting rid of old dead
code.  This stuff is either commented out or inside '#if 0' so it is not
currently in use at all, let's just get rid of it once and for all.  That's a
few lines less to deal with.

floppy: do a very minimal style cleanup of the floppy driver

2007-10-17T15:43:03+00:00

Yes, some of this will likely be replaced in later patches, but I do not see
anyone else coming out of the woodwork with any patches for this driver, so
I'll ignore comments about churn.  I want to get this driver cleaned up, and
if I'm going to do so I want to start with this basic style cleanup to reduce
the reading pain a bit.

floppy: tolerate DMA channel unavailability

2007-10-17T15:42:55+00:00

The floppy driver is already written to be able to operate in virtual DMA
mode.  Thus it can easily be adjusted to tolerate failure from
fd_request_dma() as long as virtual DMA mode is not disallowed.

Drop 'size' argument from bio_endio and bi_end_io

2007-10-10T07:25:57+00:00

As bi_end_io is only called once when the reqeust is complete,
the 'size' argument is now redundant.  Remove it.

Now there is no need for bio_endio to subtract the size completed
from bi_size.  So don't do that either.

While we are at it, change bi_end_io to return void.

Introduce rq_for_each_segment replacing rq_for_each_bio

2007-10-10T07:25:56+00:00

Every usage of rq_for_each_bio wraps a usage of
bio_for_each_segment, so these can be combined into
rq_for_each_segment.

We define "struct req_iterator" to hold the 'bio' and 'index' that
are needed for the double iteration.

[BLOCK] Get rid of request_queue_t typedef

2007-07-24T07:28:11+00:00

Some of the code has been gradually transitioned to using the proper
struct request_queue, but there's lots left. So do a full sweet of
the kernel and get rid of this typedef and replace its uses with
the proper type.
