Subject: [PATCH v2 1/5] bitmap: Make bitmap_remap() and bitmap_bitremap() available to users
Date: Mon, 10 May 2021 22:46:29 +0300 [thread overview]
Message-ID: <20210510194633.11943-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210510194633.11943-1-andriy.shevchenko@linux.intel.com>
Currently the bitmap_remap() and bitmap_bitremap() are available
only for CONFIG_NUMA=y case, while some users may benefit out of it
and being independent to NUMA code. Make them available to users
by moving out of ifdeffery and exporting for modules.
