filesystems - Not compiling the whole kernel only part of it -


my interest towards understanding linux kernel. filesystem. i'm doing is, i've placed "printk" statements in files(such inode.c, ialloc.c, etc.) in fs/ext3/ folder in kernel source code.

so want instead of compiling whole kernel, want compile part concerned ext3 filesystem. there way compile part in have made changes in debian based systems (i'm using ubuntu 14.04). have wait whole kernel compile unnecessarily though i've made changes small part of it. please me in regard.

p.s.- i've searched internet , found links too. not satisfactory. steps indicate compiling complete kernel instead.

i have assumed have modified fs/ext3/inode.c

suppose kernel source directory linux-x.x.x change directory

cd linux-x.x.x

to compile particular file

make ./fs/ext3/inode.o

only particular file compiled . same files have changed.
