[PATCH] selftests: ublk: Use ARRAY_SIZE() macro to improve code

by Akhilesh Patil

Use ARRAY_SIZE() macro while calculating size of an array to improve code readability and reduce potential sizing errors. Implement this suggestion given by spatch tool by running coccinelle script - scripts/coccinelle/misc/array_size.cocci Follow ARRAY_SIZE() macro usage pattern in ublk.c introduced by, commit ec120093180b9 ("selftests: ublk: fix ublk_find_tgt()") wherever appropriate to maintain consistency.

[PATCH v4 0/5] Better split_huge_page_test result check

by Zi Yan

This patchset uses kpageflags to get after-split folio orders for a better split_huge_page_test result check[1]. The added gather_after_split_folio_orders() scans through a VPN range and collects the numbers of folios at different orders. check_after_split_folio_orders() compares the result of gather_after_split_folio_orders() to a given list of numbers of different orders. This patchset also added new order and in folio offset to the split huge page debugfs's pr_debug()s; Changelog === From V3[4]: 1. Renamed {gather,check}_folio_orders() to {gather,check}_after_split_folio_orders() and moved them to split_huge_page_test.c, since both functions are not general enough for arbitrary folio order checks in any virtual address range. Comments are added to clarify the purpose of these functions. 2. Fixed file descriptor error check. 3. Removed unnecessary statements. 4. Fixed is_backed_by_folio() tail PFN off-by-one check issue. 5. Added a check in is_backed_by_folio() to detect if the order of the backing large folio is larger than the given order. 6. Moved misplaced comments in is_backed_by_folio(). 7. Added a comment and a commit message to clarify why the split range of folio_split() tests is changed. From V2[3]: 1. Added two missing free()s in check_folio_orders(). 2. Reimplemented is_backed_by_thp() to use kpageflags to get precise folio order information and renamed it to is_backed_by_folio() in new Patch 3. 3. Renamed *_file to *_fd in Patch 2. 4. Indentation fixes. 5. Fixed vaddr stepping issue in gather_folio_orders() when a compound tail page is encountered. 6. Used pmd_order in place of max_order in split_huge_page_test.c. 7. Documented gather_folio_orders(). From V1[2]: 1. Dropped split_huge_pages_pid() for loop step change to avoid messing up with PTE-mapped THP handling. split_huge_page_test.c is changed to perform split at [addr, addr + pagesize) range to limit one folio_split() per folio. 2. Moved pr_debug changes in Patch 2 to Patch 1. 3. Moved KPF_* to vm_util.h and used PAGEMAP_PFN instead of local PFN_MASK. 4. Used pagemap_get_pfn() helper. 5. Used char *vaddr and size_t len as inputs to gather_folio_orders() and check_folio_orders() instead of vpn and nr_pages. 6. Removed variable length variables and used malloc instead.

[PATCHv2 net-next 0/3] bonding: support aggregator selection based on port priority

by Hangbin Liu

This patchset introduces a new per-port bonding option: `ad_actor_port_prio`. It allows users to configure the actor's port priority, which can then be used by the bonding driver for aggregator selection based on port priority. This provides finer control over LACP aggregator choice, especially in setups with multiple eligible aggregators over 2 switches. v2: a) set default bond option value for port priority (Nikolay Aleksandrov) b) fix __agg_ports_priority coding style (Nikolay Aleksandrov) c) fix shellcheck warns Hangbin Liu (3): bonding: add support for per-port LACP actor priority bonding: support aggregator selection based on port priority selftests: bonding: add test for LACP actor port priority Documentation/networking/bonding.rst | 18 +++- drivers/net/bonding/bond_3ad.c | 29 ++++++ drivers/net/bonding/bond_netlink.c | 16 ++++ drivers/net/bonding/bond_options.c | 37 ++++++++ include/net/bond_3ad.h | 2 + include/net/bond_options.h | 1 + include/uapi/linux/if_link.h | 1 + .../selftests/drivers/net/bonding/Makefile | 3 +- .../drivers/net/bonding/bond_lacp_prio.sh | 93 +++++++++++++++++++ tools/testing/selftests/net/forwarding/lib.sh | 24 ----- tools/testing/selftests/net/lib.sh | 24 +++++ 11 files changed, 222 insertions(+), 26 deletions(-) create mode 100755 tools/testing/selftests/drivers/net/bonding/bond_lacp_prio.sh -- 2.50.1
