From: Christophe JAILLET Date: Thu, 25 Nov 2021 19:42:51 +0000 (+0100) Subject: RDMA/mlx4: Use bitmap_alloc() when applicable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0c83da72d0c98cbde21fee4d0e8a7f3b5cac273a;p=linux.git RDMA/mlx4: Use bitmap_alloc() when applicable Use 'bitmap_alloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.
