Subject: rust: alloc: cleanup doctest imports to "kernel vertical" style
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=ec51531fb8efda9b75316111c040dd756f815b0c;p=thirdparty%2Fkernel%2Flinux.git

rust: alloc: cleanup doctest imports to "kernel vertical" style

Change all imports in the alloc module's doctests to use the "kernel
vertical" import style [1].

While at it, drop imports that are automatically included in doctests.
