Description of problem: There are options which are not documented within the man page. Version-Release number of selected component (if applicable): blockdev (util-linux 2.13-pre7) How reproducible: always Steps to Reproduce: 1. blockdev --help 2. man blockdev Actual results: # blockdev --help Usage: blockdev -V blockdev --report [devices] blockdev [-v|-q] commands devices Available commands: --getsz (get size in 512-byte sectors) --setro (set read-only) --setrw (set read-write) --getro (get read-only) --getss (get sectorsize) --getbsz (get blocksize) --setbsz BLOCKSIZE (set blocksize) --getsize (get 32-bit sector count) --getsize64 (get size in bytes) --setra READAHEAD (set readahead) --getra (get readahead) --flushbufs (flush buffers) --rereadpt (reread partition table) --rmpart PARTNO (disable partition) --rmparts (disable all partitions) man blockdev: BLOCKDEV(8) BLOCKDEV(8) NAME blockdev - call block device ioctls from the command line SYNOPSIS blockdev [options] commands devices DESCRIPTION The utility blockdev allows one to call block device ioctls from the command line. OPTIONS -V Print version and exit. -q Be quiet. -v Be verbose. COMMANDS --setro Set read-only. --setrw Set read-write. --getro Get read-only. Print 1 if the device is read-only, 0 otherwise. --getss Print sectorsize in bytes - usually 512. --getsize Print device capacity (in 512-byte sectors). --setra N Set readahead to N 512-byte sectors. --getra Print readahead (in 512-byte sectors). --flushbufs Flush buffers. --rereadpt Reread partition table.
