mtd: Add several functions to the fail_function list
add mtd_read(), mtd_write(), mtd_erase(), mtd_block_markbad() to
fail_function list for testing purpose
- Specify the function to inject the fault
echo mtd_read > /sys/kernel/debug/fail_function/inject
- Specifies the return value of the function to inject the fault
printf %#x -12 > /sys/kernel/debug/fail_function/mtd_read/retval
- Specify other fault injection configuration parameters.
echo -1 > /sys/kernel/debug/fail_function/times
echo 100 > /sys/kernel/debug/fail_function/probability
echo 15 > /sys/kernel/debug/fail_function/space
