gdb: lx-symbols: do not error out on monolithic build (2024-11-14 22:51:14 -0800) ---------------------------------------------------------------- - The series "resource: A couple of cleanups" from Andy Shevchenko performs some cleanups in the resource management code. - The series "Improve the copy of task comm" from Yafang Shao addresses possible race-induced overflows in the management of task_struct.comm[]. - The series "Remove unnecessary header includes from {tools/}lib/list_sort.c" from Kuan-Wei Chiu adds some cleanups and a small fix to the list_sort library code and to its selftest. - The series "Enhance min heap API with non-inline functions and optimizations" also from Kuan-Wei Chiu optimizes and cleans up the min_heap library code. - The series "nilfs2: Finish folio conversion" from Ryusuke Konishi finishes off nilfs2's folioification. - The series "add detect count for hung tasks" from Lance Yang adds more userspace visibility into the hung-task detector's activity. - Apart from that, singelton patches in many places - please see the individual changelogs for details. ---------------------------------------------------------------- Alexandru Ardelean
