I hope this will help in finding the problem. drbd_worker.c: In function `w_e_end_rsdata_req': drbd_worker.c:619: warning: implicit declaration of function `page_count' drbd_receiver.c: In function `drbd_put_ee': drbd_receiver.c:346: warning: implicit declaration of function `page_count' This is the entry in the mm.h file #define is_page_cache_freeable(page) (page_count(page) - !!page->buffers == 1) So I put #include <linux/mm.h> in the drbd_reciever.c file as well. But the problem persists. I also tried using 0.6.13 and got the same error. I then tried it on RH Enterprise 3 Workstation and got the same thing.
