atomic_inc( & users using this buffer_head )

**Caller**
Name	Describe
__find_get_block_slow	Various filesystems appear to want __find_get_block to be non-blocking
osync_buffers_list	sync is designed to support O_SYNC io
fsync_buffers_list
__bread_slow
bh_lru_install	Install a buffer_head into this cpu's LRU. If not already in the LRU, it is* inserted at the front, and the buffer_head at the back if any is evicted.* Or, if already in the LRU it is moved to the front.
lookup_bh_lru	Look up the bh in this cpu's LRU. If it's there, move it to the head.
ll_rw_block	ll_rw_block: low-level access to block devices (DEPRECATED)@op: whether to %READ or %WRITE@op_flags: req_flag_bits@nr: number of &struct buffer_heads in the array@bhs: array of pointers to &struct buffer_head* ll_rw_block() takes an array of pointers
write_dirty_buffer
__sync_dirty_buffer	For a data-integrity writeout, we need to wait upon any in-progress I/O* and then start new I/O and then wait upon it. The caller must have a ref on* the buffer_head.
bh_submit_read	h_submit_read - Submit a locked buffer for reading@bh: struct buffer_head Returns zero on success and -EIO on error.
