This patchset contains 2 patches: [PATCH 1/2] xfstests: replace hexdump with od command [PATCH 2/2] fstests: test dirty pipe vulnerability issue of CVE-2022-0847 I've sent the V2 [2/2] last week[1], but due to the [2/2] hasn't been merged and the [1/2] will affect [2/2]. So I send these two patches in one patchset this time. Just please note, the [2/2] is the last version. [1] https://lore.kernel.org/fstests/20220320123932.1000005-1-zlang@xxxxxxxxxx/ Thanks, Zorro
