The patch titled Subject: lib: bitmap: make nbits parameter of bitmap_subset unsigned has been removed from the -mm tree. Its filename was lib-bitmap-make-nbits-parameter-of-bitmap_subset-unsigned.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx> Subject: lib: bitmap: make nbits parameter of bitmap_subset unsigned The compiler can generate slightly smaller and simpler code when it knows that "nbits" is non-negative. Since no-one passes a negative bit-count, this shouldn't affect the semantics.
