The patch titled Subject: lib/test_printf.c: add test for large bitmaps has been added to the -mm tree. Its filename is lib-test_printfc-add-test-for-large-bitmaps.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/lib-test_printfc-add-test-for-large-bitmaps.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/lib-test_printfc-add-test-for-large-bitmaps.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/test_printf.c: add test for large bitmaps Following "lib/vsprintf.c: expand field_width to 24 bits", let's add a test to see that we now actually support bitmaps with 65536 bits.
