Subject: XArray: Include bitmap.h from xarray.h
X-Git-Tag: xarray-5.18~2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=22f56b8e890d4e2835951b437bb6eeebfd1cb18b;p=users%2Fwilly%2Fxarray.git

XArray: Include bitmap.h from xarray.h

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")
