Yonghong Song b123480eec docs/bpf: Document some special sdiv/smod operations ... Patch [1] fixed possible kernel crash due to specific sdiv/smod operations in bpf program. The following are related operations and the expected results of those operations: - LLONG_MIN/-1 = LLONG_MIN - INT_MIN/-1 = INT_MIN - LLONG_MIN%-1 = 0 - INT_MIN%-1 = 0 Those operations are replaced with codes which won't cause kernel crash. This patch documents what operations may cause exception and what replacement operations are.
