| |
The added disk_start_io_acct() function declaration causes a warning when CONFIG_BLOCK is disabled:
include/linux/blkdev.h:1895:41: error: declaration of 'struct gendisk' will not be visible outside of this function [-Werror,-Wvisibility]
Declare the struct tag before the function to suppress that warning.
