perf test: Move each test suite struct to its test

2021-11-13T13:30:58+00:00

Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.

Committer notes:

Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

Rename bitmap_alloc() to bitmap_zalloc() in tools to follow the bitmap API
in the kernel.

No functional changes intended.

perf env: Remove needless cpumap.h header

2019-09-20T12:19:21+00:00

Only a 'struct perf_cmp_map' forward allocation is necessary, fix the
places that need the header but were getting it indirectly, by luck,
from env.h.

perf env: Remove env.h from other headers where just a fwd decl is needed

2019-08-31T22:10:40+00:00

And fixup the fallout of c files not building due to now missing
headers.

perf cpumap: Remove needless includes from cpumap.h

2019-08-22T20:16:57+00:00

The util/cpumap.h file doesn't use anything in refcount.h not in
debug.h, it needs just a forward reference to 'struct cpu_map_data',
that is defined in util/event.h and cpumap.h was getting indirectly via,
of all things, debug.h

perf tools: Use zfree() where applicable

2019-07-09T13:13:27+00:00

In places where the equivalent was already being done, i.e.:

   free(a);
   a = NULL;

And in placs where struct members are being freed so that if we have
some erroneous reference to its struct, then accesses to freed members
will result in segfaults, which we can detect faster than use after free
to areas that may still have something seemingly valid.
