[SCSI] sr: consider the last written sector when determining media size

2009-10-02T14:45:46Z

On certain cases, UDF disc doesn't report capacity correctly via READ_CAPACITY but TOC or trackinfo contains valid information which can be obtained using cdrom_get_last_written(). ide-cd considers both values and uses the larger one. Do the same in sr. This fixes bko#9668. http://bugzilla.kernel.org/show_bug.cgi?id=9668 Signed-off-by: Tejun Heo Reported-by: Milan Kocian Cc: Jan Kara Signed-off-by: James Bottomley

sd, sr: fix Driver 'sd' needs updating message

2009-06-21T17:01:27Z

If a SCSI ULD driver sets blk_queue_prep_rq(), it should clean it up itself on remove(), and not from the bus callbacks. This removes the need to hook into bus->remove(), which should not be used at the same time as driver->remove().

block: Do away with the notion of hardsect_size

2009-05-22T21:22:54Z

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: Martin K.

block: convert to pos and nr_sectors accessors

2009-05-11T07:50:54Z

With recent cleanups, there is no place where low level driver directly manipulates request fields. This means that the 'hard' request fields always equal the !hard fields. Convert all rq->sectors, nr_sectors and current_nr_sectors references to accessors. While at it, drop superflous blk_rq_pos() < 0 test in swim.c.

[SCSI] fix recovered error handling

2009-04-03T14:22:55Z

We have a problem with recovered error handling in that any command which goes down as BLOCK_PC but which returns a sense code of RECOVERED ERROR gets completed with -EIO. For actual SG_IO commands, this doesn't matter at all, since the error return code gets dropped in favour of req->errors which contain the SCSI completion code. However, if this command is part of the block system, then it will pay attention to the returned error code. In particularly if a SYNCHRONIZE CACHE from a barrier command completes with RECOVERED ERROR, the resulting -EIO on the barrier causes block to error the request and return it to the filesystem. Fix this by converting the -EIO for recovered error to zero, plus remove the printing of this from sd and sr so the message isn't double printed. Signed-off-by: James Bottomley

[SCSI] add residual argument to scsi_execute and scsi_execute_req

2008-12-29T17:24:24Z

scsi_execute() and scsi_execute_req() discard the residual length information. Some callers need it. This adds residual argument (optional) to scsi_execute and scsi_execute_req. Signed-off-by: FUJITA Tomonori Signed-off-by: James Bottomley

[PATCH 1/2] kill FMODE_NDELAY_NOW

2008-12-04T09:22:57Z

Update FMODE_NDELAY before each ioctl call so that we can kill the magic FMODE_NDELAY_NOW. It would be even better to do this directly in setfl(), but for that we'd need to have FMODE_NDELAY for all files, not just block special files. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

[PATCH] beginning of methods conversion

2008-10-21T11:47:32Z

To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro
