| |
btrfs_err_str function is not called from anywhere and is replicated in the userspace headers for btrfs-progs.
It's removal also fixes the following linux/btrfs.h userspace compilation error:
/usr/include/linux/btrfs.h: In function 'btrfs_err_str': /usr/include/linux/btrfs.h:740:11: error: 'NULL' undeclared (first use in this function) return NULL;
Suggested-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Dmitry V. Levin <ldv@altlinux.org> Reviewed-by: David Sterba <dsterba@suse.com> --- v3: the patch seems to be lost, resending with updated list of addressees
v2: remove btrfs_err_str rather than fix it
