Theodore Ts'o 6568ba325e mke2fs: only try discarding a single block to test if discard works ... Commit d2bfdc7ff1 ("Use punch hole as "discard" on regular files") added a test to see if the storage device actually supports discard. The intent was to try discarding the first block but since io_channel_discard() interprets the offset and count arguments in blocks, and not bytes, mke2fs was actually discarding the first 16 megabytes (when the block size is 4k). This is normally not a problem, since most file systems are larger than that, and requests to discard beyond the end of the block device are ignored. However, when creating a small file system as part of a image containing multiple partitions, the initial test discard can end up discarding data beyond the file system being created.
