Subject: Re: [PATCH] mm/util: make memdup_user_nul() similar to memdup_user()
Date: Tue, 31 Dec 2024 13:13:06 +0900 [thread overview]
Message-ID: <a3e1b5a8-285b-4ed1-bbb4-7096e9efc838@I-love.SAKURA.ne.jp> (raw)

Would you prefer updating the description to something like below?
The only difference between memdup_user_nul() and memdup_user() should be
that the former appends trailing nul byte. Apply three changes in the
latter to the former.
commit 6c2c97a24f09 ("memdup_user(): switch to GFP_USER")
commit 6c8fcc096be9 ("mm: don't let userspace spam allocations warnings")
commit d73778e4b867 ("mm/util: Use dedicated slab buckets for
memdup_user()")
