Document the start and size fields (which were introduced in commit v2.5.42-215-gb288f6a) to avoid guesswork on the unit.
Signed-off-by: Peter Wu <pe...@lekensteyn.nl> --- Hi, As the meaning has not changed for over 13 years, I would like to formalize these attributes such that users can rely on it[1][2]. The sector definition was inspired by the block/stat.txt documentation. By the way, the ABI/README document is ambiguous on the meaning of "Date", is it the creation date of the documentation entry or the creation of the filesystem interface? I have chosen the latter here.
