[OS-BUILD PATCHv3 0/2] redhat: introduce RH_KABI_EXCLUDE_WITH_SIZE and enable size checks

by Sabrina Dubroca (via Email Bridge)

From: Sabrina Dubroca on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1619 This MR introduces a new kABI macro, RH_KABI_EXCLUDE_WITH_SIZE. The implementation is identical to RH_KABI_EXTEND_WITH_SIZE, but the meaning is more in line with RH_KABI_EXCLUDE. The size check and reserved space allows us to exclude an element embedded inside a kABI-protected structure while reserving space for it to grow in the future. The size checks that are part of multiple kABI macros are currently not enabled because the config option to turn them on is missing. Those size checks only make sense on regular builds, so they're disabled on debug kernels.

Fedora kernel emails: too much or just right?

by Donald Zickus

Hi, It has been awhile since we changed how this mailing list is used. As folks have noticed, we have increased traffic significantly over the past couple of years to reflect the activity Red Hat developers are performing on the Fedora kernel. My question to this list is around the thoughts of this activity: * Is there too much noise? Should we throttle back? * is the volume ok? Folks have good filters? * Other suggestions on how we use this list? Trying to continue to make this mailing list useful. Thanks for any feedback! Cheers, Don

[OS-BUILD PATCHv3] mm/sparsemem: Fix 'mem_section' will never be NULL gcc 12 warning

by Justin M. Forbes (via Email Bridge)

From: Waiman Long <longman(a)redhat.com> mm/sparsemem: Fix 'mem_section' will never be NULL gcc 12 warning The gcc 12 compiler reports a "'mem_section' will never be NULL" warning on the following code: static inline struct mem_section *__nr_to_section(unsigned long nr) { #ifdef CONFIG_SPARSEMEM_EXTREME if (!mem_section) return NULL; #endif if (!mem_section[SECTION_NR_TO_ROOT(nr)]) return NULL; : It happens with both CONFIG_SPARSEMEM_EXTREME on and off. The mem_section definition is #ifdef CONFIG_SPARSEMEM_EXTREME extern struct mem_section **mem_section; #else extern struct mem_section mem_section[NR_SECTION_ROOTS][SECTIONS_PER_ROOT]; #endif In the CONFIG_SPARSEMEM_EXTREME case, mem_section obviously cannot be NULL, but *mem_section can be if memory hasn't been allocated for the dynamic mem_section[] array yet. In the !CONFIG_SPARSEMEM_EXTREME case, mem_section is a static 2-dimensional array and so the check "!mem_section[SECTION_NR_TO_ROOT(nr)]" doesn't make sense. Fix this warning by checking for "!*mem_section" instead of "!mem_section" and moving the "!mem_section[SECTION_NR_TO_ROOT(nr)]" check up inside the CONFIG_SPARSEMEM_EXTREME block.

[OS-BUILD PATCHv5 0/4] Sync support status with RHEL9 and updates to new messaging

by pjgeorg (via Email Bridge)

From: pjgeorg on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1610 Some details about this series: * Commits 06218335 to e1eb4b24 forward port commits to use new messaging introduced in cf796e6a. * Commits d5867f81 to 3f858e49 add missing #ifdef CONFIG_RHEL_DIFFERENCES guards. * Commit 47f7c2f5 fixes a typo in cf796e6a. * Commits efeb0057 to 0f1c6113 update a few more drivers to use the new messaging introduced in cf796e6a. Commits 5aec7a92, 02a4b827 and 67f77726 could be further improved. All of these still silently drop PCI IDs with no messaging at all. Downstream commit [ce5b1ff71108d] is not included as these modules have already been disabled in 48086994. Downstream MR [489] is also not included as it has not been merged yet.
