Dmitry Monakhov 12e9b89200 ext4: Use bitops to read/modify i_flags in struct ext4_inode_info 
At several places we modify EXT4_I(inode)->i_flags without holding
i_mutex (ext4_do_update_inode, ...). These modifications are racy and
we can lose updates to i_flags. So convert handling of i_flags to use
bitops which are atomic.
