If anyone has any objections, please let me know. ------------------ From: Zhen Ni [ Upstream commit ba941796d7cd1e81f51eed145dad1b47240ff420 ] Since the ahash_region() macro was redefined to calculate the region index solely from HTABLE_REGION_BITS, the htable_bits parameter became unused. Remove the unused htable_bits argument and its call sites, simplifying the code without changing semantics.
