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 because bitmap_parselist() is a part of user interface, and its behavior should not change.
In this patchset - bitmap_parselist_user() made a wrapper on bitmap_parselist(); - bitmap_parselist() reworked (patch 2); - time measurement in test_bitmap_parselist switched to ktime_get (patch 3); - new tests introduced (patch 4), and - bitmap_parselist_user() testing enabled with the same testset as bitmap_parselist() (patch 5).
v1: https://lkml.org/lkml/2018/12/23/50 v2: https://www.spinics.net/lists/kernel/msg3048976.html v3: Implementation of an approach with copying the data to kernel space in bitmap_parselist_user() instead of parsing user data byte by byte. For me, it looks better than v2.
