* blockdev: add --help optionSami Kerola2011-06-301-24/+23Star
| | | | | | | | The option is also accepted in format `-h'. As a side effect usage function is now able to return success, and since it had to be touched the printing is cleaned up. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* blockdev: reduce usage text widthFrancesco Cosoleto2010-03-311-4/+4
| | | | | | | | | | Use spaces in usage text instead of tabs and reduce the distance between option names and descriptions. This helps to minimize problems due to limited number of columns and translated texts which take up more space than English. Signed-off-by: Francesco Cosoleto <cosoleto@gmail.com>

* blockdev: use lib/blkdev.c, fix --reportKarel Zak2007-11-071-83/+9Star
| | | | | | | | | | This patch replaces duplicate code with blkdev_ functions from lib/blkdev.c. The patch also fix the output from "blockdev --report". The Size field was in 512-byte sectors instead in real size in bytes. Signed-off-by: Karel Zak <kzak@redhat.com>

* blockdev: use LU and LLU for BLKGETSIZE and BLKGETSIZE64Karel Zak2007-08-011-2/+28
| | | | | | | | | | | The "blkockdev --getsize" returns negative numbers on i386 for 1Tb devices. The BLKGETSIZE and BLKGETSIZE64 have to use unsigned long and unsigned long long. $ blockdev --getsize /dev/mapper/huge -2147483648 Signed-off-by: Karel Zak <kzak@redhat.com>
* blockdev: fix "blockdev --getsz" for large devicesKarel Zak2007-08-011-2/+5
| | | | | | | The "blockdev --getsz" command doesn't try to use BLKGETSIZE64 when previous BLKGETSIZE failed with EFBIG. This patch fixes this problem. Signed-off-by: Karel Zak <kzak@redhat.com>

* 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>
