[PATCH bpf-next v10 01/24] bpf: Fix early return in map_check_btf

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of returning directly with -EOPNOTSUPP for the timer case, we
need to free the btf_record before returning to userspace.

Fixes: db559117828d ("bpf: Consolidate spin_lock, timer management into btf_record")
