block: use i_size_write() in bd_set_size()
blkdev_ioctl(GETBLKSIZE) uses i_size_read() to read size of block device. If we update block size directly, reader may see intermediate result in some machines and configurations. Use i_size_write() instead. Signed-off-by: Guo Chao <yan@linux.vnet.ibm.com> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Guo Chao <yan@linux.vnet.ibm.com> Cc: M.
