Revision 55860d96ca59265d35427da0ee7d7f61e404f8e7 authored by Sebastian Andrzej Siewior on 26 June 2020, 03:29:55 UTC, committed by Linus Torvalds on 26 June 2020, 07:27:37 UTC
According to Christopher Lameter two fixes have been merged for the same
problem. As far as I can tell, the code does not acquire the list_lock
and invoke kmalloc(). list_slab_objects() misses an unlock (the
counterpart to get_map()) and the memory allocated in free_partial()
isn't used.
Revert the mentioned commit.
