* blockdev: don't use HDIO_GETGEOPhillip Susi2013-11-041-5/+15
| | | | | | | | | | | | | blockdev was still using this depreciated ioctl and that was causing blockdev --report to fail on loop and nbd devices. Switch to reading the partition start from sysfs instead. This also allows it to correctly report > 2^32 sector counts.

* Revert "blockdev: Remove the --setbsz (set blocksize) option which has never ↵Karel Zak2013-10-111-0/+7
| | | | | | | | | | | | | worked." This reverts commit b1555acc2f709ac4f3b1e6c686a11cadb7b04f72. It seems that the option is used by kernel guys to test kernel, so let's keep the option in the blockdev(8) although it's almost useless in userspace. All we need is to improve docs to make things more obvious to end users. Signed-off-by: Karel Zak <kzak@redhat.com>
* blockdev: Remove the --setbsz (set blocksize) option which has never worked.Richard W.M. Jones2013-10-081-7/+0Star
| | | | | | | | | | | | | | | | | | | This option has never worked. If you try setting the block size on a block device, and then read it using --getbsz, you will see that the block size never changes. The reason for this is because the block size is specific to the current file descriptor opening the block device, so the change of block size only persists for as long as blockdev has the device open, and is lost once blockdev exits. Also the block size is not really used anywhere. Filesystems, for example, have their own idea of block size and ignore this setting completely.

* blockdev: add BLKFRAGET/BLKFRASET ioctlsKarel Zak2007-06-291-0/+8
| | | | | | | | | | | | | | In Linux 2.6 the BLKRASET ioctl has the desired effect for mounted file-systems. In Linux 2.4 it appears to set the number of blocks to read-ahead on the *device* as opposed to within a *file*, and the maximum value of this number is 255. As a result the invocation of blockdev will fail on Linux 2.4 for any usefully large value of READAHEAD, and will not in any case have the desired affect for fragmented files. (Based on the blockdev-getfra-setfra.patch Debian patch.) Signed-off-by: Karel Zak <kzak@redhat.com>
