As create_proc_entry function is deprecated, what is its replacement?
I was trying to create a simple proc entry using create_proc_entry but got the this error:
error: implicit declaration of function ‘create_proc_entry’
I grepped create_proc_entry in proc_fs.h but didn't find it there. Is there something that I'm missing or there's alternative to do this?
The newer functions are named proc_*. You can see their declarations in include/linux/proc_fs.h.
In particular, proc_create creates a proc entry. You can check out the implementation of the other (quite useful) functions in the source file at fs/proc/generic.c. You may be particularly interested in proc_mkdir and proc_create_data.

If you need the interface for an older version, you can find the equivalent location for a previous commit. If you want the latest version, the suggestions in this answer could have become outdated.
