Constant FANOTIFY_PERM_CLASSES

pub const FANOTIFY_PERM_CLASSES: u32 = _; // 12u32

Available on crate feature dep_nc only.

Flags allowed to be passed from/to userspace.

We intentionally do not add new bits to the old FAN_ALL_* constants, because they are uapi exposed constants. If there are programs out there using these constant, the programs may break if re-compiled with new uapi headers and then run on an old kernel. Group classes where permission events are allowed
