Subject: rust: alloc: fix `Vec::extend_with` SAFETY comment
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=f497aae6ded43f91b1dbf29a35d7062823635640;p=thirdparty%2Fkernel%2Flinux.git

rust: alloc: fix `Vec::extend_with` SAFETY comment

Fix an incorrect operator in the SAFETY comment, changing `<` to `<=`,
since `Vec::reserve` guarantees capacity for exactly n additional elements,
so the equal case should be included.
