The patch titled mm/sparse.c: check the return value of sparse_index_alloc() has been removed from the -mm tree. Its filename was mm-sparsec-check-the-return-value-of-sparse_index_alloc.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: mm/sparse.c: check the return value of sparse_index_alloc() From: WANG Cong <xiyou.wangcong@xxxxxxxxx> Since sparse_index_alloc() can return NULL on memory allocation failure, we must deal with the failure condition when calling it.
