Subject: [PATCH v2 RESEND 0/6] lib: rework bitmap_parselist and tests
Date:   Tue, 26 Mar 2019 00:07:42 +0300
Message-Id: <20190325210748.6571-1-ynorov@marvell.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

bitmap_parselist has been evolved from a pretty simple idea for long and
now lacks for refactoring. It is not structured, has nested loops and a
set of opaque-named variables.

Things are more complicated than they may be because bitmap_parselist()
is a part of user interface, and its behavior should not change.

In this patchset
 - __bitmap_parselist() is reworked (patches 2 and 3);
 - time measurement in test_bitmap_parselist switched to ktime_get
   (patch 4);
 - new tests introduced (patch 5), and
 - bitmap_parselist_user() testing enabled with the same testset as
   bitmap_parselist() (patch 6).

Patches 1 and 4 are fixes and may be applied separately.

v1: https://lkml.org/lkml/2018/12/23/50
v2: https://www.spinics.net/lists/kernel/msg3048976.html
v2 RESEND: rebased on next-20190325 and retested. 

Yury Norov (6):
  bitmap_parselist: don't calculate length of the input string
  bitmap_parselist: move non-parser logic to helpers
  bitmap_parselist: rework input string parser
  lib/test_bitmap: switch test_bitmap_parselist to ktime_get()
  lib/test_bitmap: add testcases for bitmap_parselist
  lib/test_bitmap: add tests for bitmap_parselist_user
