[PATCH v2 0/9] fanotify: add support for more event types

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Jan,

This is the final part of patch series to add support for filesystem
change monitoring to fanotify.

The end game is to use:
  fd = fanotify_init(FAN_CLASS_NOTIF|FAN_REPORT_FID, ...);
  rc = fanotify_mark(fd, FAN_MARK_FILESYSTEM, FAN_CREATE|FAN_DELETE...);
to monitor changes to a large scale namespace.

This functionality was not available with inotify API, which does not
scale well with recursive directory watches and was not available
with fanotify API, which did not support directory modification events.

This patch set depends on the fsnotify prep patches posted yesterday.
The entire work based on your fsnotify branch is available on my
fanotify_dentry branch [1].

I have tested this work with some preliminary LTP tests [2] and a demo
program [3]. Matthew Bobrowski has agreed to help me with writing more
tests and man pages (thanks Matthew!).

Last patch raises a question about how to deal with FAN_ONDIR flag with
new event types and proposed a minimal viable implementation that could
be used as a base for further discussion.

Thanks,
Amir.
