From ccde70f4d4baea4d2ebc3d646a0a4ab4cfdf683c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 23 Apr 2024 17:20:24 +0300 Subject: [PATCH] xarray: use BITS_PER_LONGS() Patch series "xarray: Clean up xarray.h". Main portion of this change is to get rid of kernel.h included into other globally available headers. This decreases a dependency hell degree. The first patch makes it possible to avoid math.h to be included as bitops.h is implied by bitmap.h. This patch (of 2): Use BITS_PER_LONGS() instead of open coded variant.
