Hi, if you grep the kernel tree for the word "compliment": $ git grep compliment arch/nios2/include/asm/asm-macros.h:126: * Tests the bit in reg2 and then compliments the bit in reg2. arch/nios2/include/asm/asm-macros.h:189: * Tests the bit in reg2 and then compliments the bit in reg2. arch/nios2/include/asm/asm-macros.h:202: * Tests the bit in reg2 and then compliments the bit in reg2. arch/powerpc/platforms/pseries/mobility.c:82: * A negative value is also the two's compliment of the actual value. drivers/block/rsxx/config.c:48: * Return the compliment of the CRC to ensure compatibility drivers/block/skd_main.c:2039: /* Note that the compliment of mask is written. A 1-bit means ... you'll see that in almost all cases, the word the author meant to use was "complement", with an 'e'. I think the respective maintainer wouldn't mind a patch fixing that in their driver/subsystem. :-) Thx. -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
