Just let all users of btrfs-corrupt-block use --value and --offset, because there was never a released version of btrfs-progs with the short options available. The short options were introduced with: commit b2ada0594116f3f4458581317e226c5976443ad0 Author: Boris Burkov <boris@bur.io> Date: Tue Jul 26 13:43:23 2022 -0700 btrfs-progs: corrupt-block: corrupt generic item data And then replacing them with long options happened in this commit: commit 22ffee3c6cf2e6f285e6fd6cb22b88c02510e10e Author: David Sterba <dsterba@suse.com> Date: Wed Jul 27 20:47:57 2022 +0200 btrfs-progs: corrupt-block: use only long options for value and offset Both commits landed in btrfs-progs 5.19, meaning there are no released versions with the short options. The reason btrfs/290 is using the short options is because the btrfs-progs patch had just been submitted shortly before the test case was added. However what we need is to have a _require_* helper that will make the test btrfs/290 not run if we're using a btrfs-progs version without those new options.

They are together in 5.19; they should have merged instead. If any backports (which I doubt), should occur both patches. Although I looked for the commits, I didn't notice that there isn't a release with the short option. Thanks! I found it ugly too, but I had no better solution. Now, it's a relief that we don't need it anymore. > However what we need is to have a _require_* helper that will make the > test btrfs/290 not run if we're using a btrfs-progs version without > those new options.

As btrfs-corrupt-block now uses --value instead of -v, and --offset instead of -o, provide backward compatibility for the testcases, by storing the option to be used in BTRFS_CORRUPT_BLOCK_OPT_VALUE and BTRFS_CORRUPT_BLOCK_OPT_OFFSET. Also, removes the stdout and stderr redirection to /dev/null.
