Revision 4249a05ff670e7b1aeea77f1a5451080ea86c88d authored by Alexey Romanov on 13 October 2022, 11:28:25 UTC, committed by Andrew Morton on 21 October 2022, 04:27:21 UTC 
zsmalloc: zs_destroy_pool: add size_class NULL check
 
Inside the zs_destroy_pool() function, there can still be NULL size_class
pointers: if when the next size_class is allocated, inside
zs_create_pool() function, kzalloc will return NULL and handling the error
condition, zs_create_pool() will call zs_destroy_pool().
