Subject: [PATCH rdma-next v4 0/3] overflow.h: Add left-shift helper
Date: Wed, 1 Aug 2018 14:25:38 -0700 [thread overview]
Message-ID: <20180801212541.22889-1-keescook@chromium.org> (raw)
This adds the left-shift overflow helper, selftests, and first usage.
-Kees
v4:
- actually fix docs typo
- rename to check_shl_overflow()
v3:
- add even more test cases (type mismatches, more signed overflows).
- fix documentation typo on argument name.
v2:
- swap out selftests with framework from Rasmus, add lots more tests.
- drop double-assignment in helper.
