[PATCH 1/2] kill FMODE_NDELAY_NOW

2008-12-04T09:22:57+00:00

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] Fix block dev compat ioctl handling

2008-12-04T09:22:55+00:00

Commit 33c2dca4957bd0da3e1af7b96d0758d97e708ef6 (trim file propagation in block/compat_ioctl.c) removed the handling of some ioctls from compat_blkdev_driver_ioctl. That caused them to be rejected as unknown by the compat layer. Signed-off-by: Andreas Schwab Cc: Al Viro Signed-off-by: Al Viro

compat_blkdev_driver_ioctl: Remove unused variable warning

2008-10-23T17:28:25+00:00

Variable 'ret' is no longer used. Don't declare it. Signed-off-by: Linus Torvalds

[PATCH] kill the rest of struct file propagation in block ioctls

Now we can switch blkdev_ioctl() block_device/mode Signed-off-by: Al Viro

[PATCH] get rid of blkdev_locked_ioctl()

2008-10-21T11:49:10+00:00

Most of that stuff doesn't need BKL at all; expand in the (only) caller, merge the switch into one there and leave BKL only around the stuff that might actually need it. Signed-off-by: Al Viro

... and remove the handling of cases when it falls back to native without changing arguments. Signed-off-by: Al Viro

[PATCH] end of methods switch: remove the old ones

[PATCH] beginning of methods conversion

2008-10-21T11:47:32+00:00

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

Add BLKDISCARD ioctl to allow userspace to discard sectors

2008-10-09T06:56:02+00:00

We may well want mkfs tools to use this to mark the whole device as unwanted before they format it, for example. The ioctl takes a pair of uint64_ts, which are start offset and length in _bytes_. Although at the moment it might make sense for them both to be in 512-byte sectors, I don't want to limit the ABI to that. Signed-off-by: David Woodhouse Signed-off-by: Jens Axboe

Fix misuses of bdevname()

2008-05-13T15:02:26+00:00

bdevname() fills the buffer that it is given as a parameter, so calling strcpy() or snprintf() on the returned value is redundant (and probably not guaranteed to work - I don't think strcpy and snprintf support overlapping buffers.)
