This is ONLY a hint for finding the header files in the /usr/src/linux directory. I do generally like this.
find include -type f | xargs grep "kthread_run"
Replace "kthread_run" with new strings for searching. This is ONLY a HINT but you asked for clear explanation.

I keep getting "implicit declaration of <some function>" error quite
often. So I'm assuming I am not adding the correct header files when I
am writing the module.
eg. I wanted to create a kernel thread using
ktheard_create/kthread_run, but couldn't find which header to include.
While I was looking for solutions I stumbled upon ctags. It mostly
gets the job done, but not always. I couldn't find the proper header
to use for open(inode,file); even though ctags pointed me to
<linux/fs.h>, I still get the implicit declaration error.
Is there any way of finding exactly which headers to include when one
is trying to use a function? A detailed explanation would be really
great.
