From: Christophe JAILLET Date: Thu, 25 Nov 2021 20:05:40 +0000 (+0100) Subject: RDMA/pvrdma: Use bitmap_zalloc() when applicable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=67ec0fdfc5de1d14b438402c6e9759da73c5c9eb;p=linux.git RDMA/pvrdma: Use bitmap_zalloc() when applicable Use 'bitmap_zalloc()' 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.
