------------------------------------------------------
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.
