fibdrv

Linux kernel module that creates device /dev/fibonacci. Writing to this device should have no effect, however reading at offset k should return the kth fibonacci number.

fibdrv's Issues

Make error causes by diff

Error occur while doing make check after I change fib_write() (the out file will be different with scripts/expected.txt)

@diff -u out scripts/expected.txt && $(call pass)

make: *** [Makefile:40：check] 錯誤 1
The proccess will stop.

Instead of removing the line, I modify it to

-@diff -u out scripts/expected.txt && $(call pass)

the error will be ignored.
make: [Makefile:40：check] 錯誤 1 (已忽略）
And the proccess will therefore continue.
