Just in case... This series conflicts with (imo very important) changes
from David,
[PATCH v2 0/3] kernel/events/uprobes: uprobe_write_opcode() rewrite
https://lore.kernel.org/all/20250318221457.3055598-1-david@redhat.com/
I think they should be merged first.
(and I am not sure yet, but it seems that we should cleanup (fix?) the
update_ref_ctr() logic before other changes).
Oleg.
