aa485e8789d56a4573f7c8d000a182b749eaa64d | Analyze and fix the following issue in the Linux kernel code: libbpf: Fix null pointer dereference in btf_dump__free on allocation failure | Problem Details:
When btf_dump__new() fails to allocate memory for the internal hashmap
(btf_dump->type_names), it returns an error code. However, the cleanup
function btf_dump__free() does not check if btf_dump->type_names is NULL
before attempting to free it. This leads to a null pointer dereference
when btf_dump__fr... | ```diff

If we are propagating across the userns boundary, we need to lock the
mounts added there. However, in case when something has already
been mounted there and we end up sliding a new tree under that,
the stuff that had been there before should not get locked.
IOW, lock_mnt_tree() should be called befor... | ```diff

collect_mounts() has several problems - one can't iterate over the results
