Zhengxu Zhang 940d156e3c exfat: fdatasync flag should be same like generic_write_sync() ... [ Upstream commit 2f2d42a17b ] Test: androbench by default setting, use 64GB sdcard. the random write speed: without this patch 3.5MB/s with this patch 7MB/s After patch "11a347fb6cef", the random write speed decreased significantly. the .write_iter() interface had been modified, and check the differences with generic_file_write_iter(), when calling generic_write_sync() and exfat_file_write_iter() to call vfs_fsync_range(), the fdatasync flag is wrong, and make not use the fdatasync mode, and make random write speed decreased. So use generic_write_sync() instead of vfs_fsync_range().
