The patch titled Subject: lib: bitmap: make nbits parameter of bitmap_complement unsigned has been added to the -mm tree. Its filename is lib-bitmap-make-nbits-parameter-of-bitmap_complement-unsigned.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/lib-bitmap-make-nbits-parameter-of-bitmap_complement-unsigned.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/lib-bitmap-make-nbits-parameter-of-bitmap_complement-unsigned.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx> Subject: lib: bitmap: make nbits parameter of bitmap_complement 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.
