The patch titled Subject: lib: bitmap: make the start index of bitmap_set unsigned has been removed from the -mm tree. Its filename was lib-bitmap-make-the-start-index-of-bitmap_set-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 the start index of bitmap_set unsigned The compiler can generate slightly smaller and simpler code when it knows that "start" is non-negative. Also, use the names "start" and "len" for the two parameters in both header file and implementation, instead of the previous mix.
