Hi,
sorry if this is a newbie question. I am newbie.

In my kernel driver, I get device id by converting struct inode struct
to btrfs_inode, I use the code:
struct btrfs_inode *btrfsInode;
btrfsInode = BTRFS_I(inode);

I usually download kernel-headers rpm package, this is not enough. it
fails to find the btrfs header files.

I had to download them not via rpm package and declare:
#include "/data/kernel/linux-4.1.21-x86_64/fs/btrfs/ctree.h"
#include "/data/kernel/linux-4.1.21-x86_64/fs/btrfs/btrfs_inode.h"

This is not good, why ctree.h and btrfs_inode.h are not in kernel headers?
Is there another package i need to download in order to get them, in
addition to kernel-headers? ?


I see they are not provided in kernel-header package, e.g:
https://rpmfind.net/linux/RPM/fedora/23/x86_64/k/kernel-headers-4.2.3-300.fc23.x86_64.html

Thanks!
