[Drbd-dev] [PATCH 03/21] drbd: use seq_put instead of seq_print where possible

[Fabian Frederick]

seq_putc/seq_puts give the following improvements:

text   data  bss    dec	    hex	filename
4661      0  8	   4669	   123d	drivers/block/drbd/drbd_proc.o
4603      0  8	   4611	   1203	drivers/block/drbd/drbd_proc-after.o
