ext4: Use bitops to read/modify EXT4_I(inode)->i_state
At several places we modify EXT4_I(inode)->i_state without holding i_mutex (ext4_release_file, ext4_bmap, ext4_journalled_writepage, ext4_do_update_inode, ...). These modifications are racy and we can lose updates to i_state. So convert handling of i_state to use bitops which are atomic.
