Change Details

print_mask_arg(), used by, e.g., the nmount(2) handler, will unconditionally call the decoder, which can lead to weird results as we get a 'false' return and consider that invalid, even if it's simply the case that there legitimately weren't any flags to decode. Check the value up-front in print_mask_arg() like we do in the other print_mask_* functions, turning this: nmount(0x6991e009000,0x8,0<><invalid>0) into: nmount(0x6991e009000,0x8,0)

Some callers are using print_mask_arg() when they should be using print_mask_arg0(); the latter should be used when all flags are optional and there's not a flag to be decoded with a 0-mask. This turns: nmount(0x6991e009000,0x8,0<><invalid>0) into: nmount(0x6991e009000,0x8,0)
