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. https://bugzilla.kernel.org/show_bug.cgi?id=15792 Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
