    libceph: small changes to messenger.c · 5821bd8c
    Alex Elder 提交于
    This patch gathers a few small changes in "net/ceph/messenger.c":
      out_msg_pos_next()
        - small logic change that mostly affects indentation
      write_partial_msg_pages().
        - use a local variable trail_off to represent the offset into
          a message of the trail portion of the data (if present)
        - once we are in the trail portion we will always be there, so we
          don't always need to check against our data position
        - avoid computing len twice after we've reached the trail
        - get rid of the variable tmpcrc, which is not needed
        - trail_off and trail_len never change so mark them const
        - update some comments
      read_partial_message_bio()
        - bio_iovec_idx() will never return an error, so don't bother
          checking for it
