This is automatically done when you use git send-email unless you pass the --no-thread option. The following command should do the trick: git send-email /*.patch Best Regards, Boris On Fri, 25 Sep 2015 06:34:34 +0000 Peter Pan 潘栋 (peterpandong) wrote: > Currently nand_bbt.c is tied with struct nand_chip, and it makes other > NAND family chips hard to use nand_bbt.c.
