[Qemu-devel] [PATCH v20 1/7] xbitmap: Introduce xbitmap

2017-12-19 Thread Wei Wang
From: Matthew Wilcox The eXtensible Bitmap is a sparse bitmap representation which is efficient for set bits which tend to cluster. It supports up to 'unsigned long' worth of bits, and this commit adds the bare bones -- xb_set_bit(), xb_clear_bit() and xb_test_bit(). Signed-off-by: Wei Wang Cc
