lib: use KSTM_MODULE_GLOBALS macro in kselftest drivers

2021-02-15T10:01:42+00:00

Instead of defining the total/failed test counters manually,
test drivers that are clients of kselftest should use the
macro created for this purpose.

test_bitmap: remove user bitmap tests

2020-09-09T02:21:33+00:00

We can't run the tests for userspace bitmap parsing if set_fs() doesn't
exist, and it is about to go away for x86, powerpc with other major
architectures to follow.

lib/test_bitmap.c: add test for bitmap_cut()

2020-08-12T17:57:59+00:00

Inspired by an original patch from Yury Norov: introduce a test for
bitmap_cut() that also makes sure functionality is as described for
partially overlapping src and dst.

lib/test_bitmap.c: make use of EXP2_IN_BITS

2020-04-07T17:43:43+00:00

Commit 30544ed5de43 ("lib/bitmap: introduce bitmap_replace() helper")
introduced some new test cases to the test_bitmap.c module.  Among these
it also introduced an (unused) definition.  Let's make use of
EXP2_IN_BITS.

lib: new testcases for bitmap_parse{_user}

2020-02-04T03:05:27+00:00

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.

lib/test_bitmap: correct test data offsets for 32-bit

2020-01-31T18:30:36+00:00

On 32-bit platform the size of long is only 32 bits which makes wrong
offset in the array of 64 bit size.

Calculate offset based on BITS_PER_LONG.

lib/bitmap: introduce bitmap_replace() helper

2019-12-05T03:44:14+00:00

In some drivers we want to have a single operation over bitmap which is
an equivalent to:

	*dst = (*old & ~(*mask)) | (*new & *mask)

Introduce bitmap_replace() helper for this.
