init_ext4_fs() calls init_ext4_proc() so we need a stub init_ext4_proc()
for the case that CONFIG_PROC_FS is not set.
Without the stub we get a build error:
fs/ext4/mballoc.c: In function 'init_ext4_proc':
fs/ext4/mballoc.c:2837: error: 'proc_root_fs' undeclared (first use in this function)
fs/ext4/mballoc.c:2837: error: (Each undeclared identifier is reported only once
fs/ext4/mballoc.c:2837: error: for each function it appears in.)
Add a stub init_ext4_proc() function that does nothing but return 0
