rule: fix element cache update in __do_add_setelems()
|
|
|
|
The set->init and expr arguments might actually refer to the same list
|
|
of elements. Skip set element cache update introduced by dd44081d91ce
|
|
("segtree: Fix add and delete of element in same batch") otherwise
|
|
list_splice_tail_init() actually operates with the same list as
|
|
arguments. Valgrind reports this problem as a memleak since the result
|
|
of this operation was an empty set element list.
|
|
|
|
Fixes: dd44081d91ce ("segtree: Fix add and delete of element in same batch")
