Subject: kvm: replace test_and_set_bit_le() in mark_page_dirty_in_slot() with set_bit_le()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b74ca3b3fd0fac08167ff96287cece56e8ca6f4d;p=openwrt%2Fstaging%2Fblogic.git

kvm: replace test_and_set_bit_le() in mark_page_dirty_in_slot() with set_bit_le()

Now that we have defined generic set_bit_le() we do not need to use
test_and_set_bit_le() for atomically setting a bit.
