Hi all,
After merging the sched-ext tree, today's linux-next build (arm_multi_v7
defconfig) failed like this:
/tmp/next/build/kernel/bpf/core.c:3379:13: error: redefinition of
'bpf_arena_handle_page_fault'
3379 | __weak bool bpf_arena_handle_page_fault(unsigned long addr, bool is_write,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from /tmp/next/build/include/linux/bpf.h:9,
from /tmp/next/build/include/linux/filter.h:9,
from /tmp/next/build/kernel/bpf/core.c:21:
/tmp/next/build/include/linux/bpf_defs.h:12:20: note: previous definition
of 'bpf_arena_handle_page_fault' with type 'bool(long unsigned int,
bool, long unsigned int)' {aka '_Bool(long unsigned int, _Bool, long
unsigned int)'}
12 | static inline bool bpf_arena_handle_page_fault(unsigned long addr, bool is_write,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Caused by commit
dc11a4dba2464 (bpf: Recover arena kernel faults with scratch page)
I have used the version from next-20260525 instead.
