[GIT PULL] notification tree

[GIT PULL] notification tree

[Eric Paris]

The notification tree has patches to address a number of fanotify
complaints from last cycle.  The most important being the (ABI
compatible) addition of 'classes' which will allow things like
hierarchical storage managers to receive events before scanners or
indexers.  It also includes default limits on the amount of memory an
fanotify listener can consume and other minor changes.  An updated
example program which makes use of most all of the fanotify feature set
can be found at

Re: [GIT PULL] notification tree

[Alexey Zaytsev]

Hi, Eric.

Now that the interface seems to be more or less set, could you please
document the new syscalls?
The last design document I could find is from 2009, and there seem to
be some updates.
