Subject: [PATCH] mdadm: Add Wimplicit-fallthrough=0 in Makefile
There are many errors like 'error: this statement may fall through'.
But the logic is right. So add the flag Wimplicit-fallthrough=0
to disable the error messages. The method I use is from
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
