iii updated this revision to Diff 357471.
iii added a comment.
- Reserve the address space "tail" in the "[TSan] Define C/C++ address ranges
for SystemZ" patch.
- Drop the "[TSan] Simulate OOM in mmap_interceptor()" patch.
- Group "[TSan] Use zeroext for function parameters" with the common code
patches.
