| |
Hi,everybody!
I am learning how to add my file system. Now ,i have add my fs called "myext2" with the magic number 0x6666 (" #define MYEXT2_SUPER_MAGIC 0x6666" in the file include/linux/myext2_fs.h)to the kernel . Myext2 is similar with ext2 but the name. And i compiled kernel successfully. And then i created my "myfs" in the type myext2
#dd if=/dev/zero of=myfs bs=1M count=1 #mkfs.ext2 myfs
The problem is after "#mkfs.ext2 myfs" ,how i can change myfs's magic number to 0x6666 but not 0xEF53 which is used by ext2?
