The patch titled Subject: lib: new testcases for bitmap_parse{_user} has been added to the -mm tree. Its filename is lib-new-testcases-for-bitmap_parse_user.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/lib-new-testcases-for-bitmap_parse_user.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/lib-new-testcases-for-bitmap_parse_user.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/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Yury Norov <yury.norov@xxxxxxxxx> Subject: lib: new testcases for bitmap_parse{_user} New version of bitmap_parse() is unified with bitmap_parse_list(), and therefore: - weakens rules on whitespaces and commas between hex chunks; - in addition to - allows passing UINT_MAX or any other big number as the length of input string instead of actual string length. The patch covers the cases.
