-stable review patch. If anyone has any objections, please let us know. --------------------- From: Jean Delvare upstream commit: f474a37bc48667595b5653a983b635c95ed82a3b Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool can be NULL and this should be tested before dereferencing it, or it can't be NULL and it shouldn't be tested at all. As far as I can see, the only case where q->pool is NULL is on early error in iscsi_pool_init(). One possible way to fix the bug is thus to not call iscsi_pool_free() in this case (nothing needs to be freed anyway) and then we can get rid of the q->pool check.
