Subject: [RFC v3 0/4] fs: Add generic file system event notifications
Date: Tue, 16 Jun 2015 15:09:29 +0200 [thread overview]
Message-ID: <1434460173-18427-1-git-send-email-b.michalska@samsung.com> (raw)
Hi All,
First of all, apologies for the delay: illness ruled out my plans
for having this out for a review as intended.
Anyway this is an updated version of the patchset for generic filesystem
events interface [1][2], hopefully handling issues raised during the previous
run.
Changes from v2:
- Switched to kref for reference counting
- Support for the events has been made optional (config option)
- Use dynamically assigned id for multicast group instead of
using static one
- Verify if there are any net listeners prior to sending the msg
- Make the interface more namespace-aware (handling mount dropped
and showing the content of config file). As for the network
namespaces - as before only the init net namespace is being
supported.
Changes from v1:
- Improved synchronization: switched to RCU accompanied with
ref counting mechanism
- Limiting scope of supported event types along with default
event codes
- Slightly modified configuration (event types followed by arguments
where required)
- Updated documentation
- Unified naming for netlink attributes
- Updated netlink message format to include dev minor:major numbers
despite the filesystem type
- Switched to single cmd id for messages
- Removed the per-config-entry ids
