[PATCH 5.17 1023/1126] XArray: Include bitmap.h from xarray.h

From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 06:30:07 EST


From: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx>

commit 22f56b8e890d4e2835951b437bb6eeebfd1cb18b upstream.

xas_find_chunk() calls find_next_bit(), which is defined in find.h,
included from bitmap.h. Inside the kernel, this isn't a problem because
bitmap.h is included from cpumask.h which is dragged in (eventually)
by gfp.h. When building the test-suite, that doesn't happen, so we need
to include bitmap.h explicitly.

Fixes: 4ade0818cf04 ("tools: sync tools/bitmap with mother linux")
