2104659 ("MEDIUM: buffer: remove the buffer_wq lock") removed
usage of the lock but not the lock itself. It's totally unused, let's
remove it.
extern struct pool_head *pool_head_buffer;
extern struct mt_list buffer_wq;
-__decl_thread(extern HA_SPINLOCK_T buffer_wq_lock);
int init_buffer();
void buffer_dump(FILE *o, struct buffer *b, int from, int to);
/* list of objects waiting for at least one buffer */
struct mt_list buffer_wq = LIST_HEAD_INIT(buffer_wq);
-__decl_aligned_spinlock(buffer_wq_lock);
/* perform minimal intializations, report 0 in case of error, 1 if OK. */
int init_buffer()
