There are a number of ffs(3) callers that do roughly: bit = ffs(val); if (bit) { do_something(bit - 1); } This pattern can be converted to ctz32() like this: zeroes = ctz32(val); if (zeroes != 32) { do_something(zeroes); } Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 1427124571-28598-6-git-send-email-stefanha@redhat.com Signed-off-by: Kevin Wolf <kwolf@redhat.com> |
