Subject: [GIT PULL] bitmap updates for 7.3
Date: Mon, 17 Aug 2026 15:38:26 -0400 [thread overview]
Message-ID: <aoNjFItGMFr5YXVe@yury> (raw)
Hi Linus,
Please pull bitmap updates for v7.3. It includes a usual set of
fixes, cleanups and performance improvements together with a
couple of new tests.
All patches spent in -next for over 3 weeks with no issues.
Thanks,
Yury

lib: test bitmap vs IDA vs Maple Tree performance for region allocations (2026-07-28 19:08:58 -0400)
----------------------------------------------------------------
bitmap updates for v7.3
- bitmap_find_next_zero_area_off() optimization (Sunyi);
- bitmap_find_next_zero_area_off(): return size when no zero area is
found (Yury);
- bitmap vs IDA vs Maple Tree performance test (Yury);
- get rid of cpumap_print_to_pagebuf() (Yury);
- use nr_node_ids in __nodemask_pr_numnodes() (Li RongQing);
- bitops: make the *_bit_le functions use unsigned long (Benjamin);
- bitmap scatter & gather test fix (Christophe);
- use __ASSEMBLER__ in bitmap header files (Thomas);
