block: introduce new block status code type

2017-06-09T15:27:32+00:00

Currently we use nornal Linux errno values in the block layer, and while
we accept any error a few have overloaded magic meanings.  This patch
instead introduces a new  blk_status_t value that holds block layer specific
status codes and explicitly explains their meaning.  Helpers to convert from
and to the previous special meanings are provided for now, but I suspect
we want to get rid of them in the long run - those drivers that have a
errno input (e.g. networking) usually get errnos that don't know about
the special block layer overloads, and similarly returning them to userspace
will usually return somethings that strictly speaking isn't correct
for file system operations, but that's left as an exercise for later.

For now the set of errors is a very limited set that closely corresponds
to the previous overloaded errno values, but there is some low hanging
fruite to improve it.

blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse
typechecking, so that we can easily catch places passing the wrong values.

Drivers: ide: remove __dev* attributes.

2013-01-03T23:57:03+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

siimage: use ->pio_mode value to determine pair device speed

2010-01-19T09:52:35+00:00

Use the current PIO mode value instead of the physical maximum one
of the pair device on the port to determine PIO commmand timings used
for both devices on the port.

siimage: use ide_dma_test_irq() (take 2)

Remove interrupt bit test (not trusted anyway) from siimage_io_dma_test_irq()
and siimage_mmio_dma_test_irq() -- this allows to replace the former function
with now identical ide_dma_test_irq()...

ide: IORDY handling fixes

2009-06-15T16:52:53+00:00

Add ide_pio_need_iordy() helper and convert host drivers to use it.

This fixes it8172, it8213, pdc202xx_old, piix, slc90e66 and siimage
host drivers to handle IORDY correctly.

ide: replace special_t typedef by IDE_SFLAG_* flags

2009-05-17T17:12:21+00:00

Replace:
- special_t typedef by IDE_SFLAG_* flags
- 'special_t special' ide_drive_t's field by 'u8 special_flags' one

There should be no functional changes caused by this patch.
